HomeInterpol Diffusion
An Interpol diffusion is a direct police-to-police request sent between countries through Interpol’s secure I-24/7 network, usually to locate, detain or obtain information about a person. A Wanted Person Diffusion (often called a red diffusion) asks other states to arrest or locate someone pending extradition. It can be sent without Interpol’s prior approval and is never published, so people usually find out only at a border, a bank or a visa office. In the UAE this can mean detention, frozen accounts and visa refusals within days.
Diffusions are challengeable. Many breach Articles 2 and 3 of Interpol’s Constitution or the Rules on the Processing of Data, and the Commission for the Control of Interpol’s Files (CCF) can order them deleted. Our team checks your status, assesses legality and prepares the appeal to fight an Interpol diffusion.
What is Interpol Wanted Person Diffusion?
Interpol Wanted Person Diffusion is a form of operational request in the Interpol system, through which one state addresses other countries to establish the whereabouts of a specific person, obtain information about them, or take temporary measures within the framework of national legislation. Unlike notices, diffusion represents an informal and expedited channel of interstate police interaction, used without prior formalization.
A diffusion does not have the legal force of an international arrest warrant and is not a court decision. It is sent directly between National Central Bureaus (NCBs) via Interpol’s secure system and is governed by Interpol’s Constitution and Rules on the Processing of Data. Unlike a Red Notice, it needs no approval from the General Secretariat before it is sent. Since 2016, however, Interpol’s Notices and Diffusions Task Force (NDTF) screens wanted person diffusions for compliance and reviews previously issued ones. The review comes after circulation, so a non-compliant diffusion can reach border and police systems before it is caught.
The main function of diffusion is to respond promptly when the requesting state needs to quickly notify other countries about the search for a person or criminal prosecution. Diffusions are used for:
- Establishing the whereabouts of the wanted person;
- A request for temporary detention within the framework of the national legislation of the recipient country;
- Obtaining information about movements, citizenship, or documents;
- Initiation of further extradition or procedural actions.
The content of diffusion is formed by the requesting party and can vary significantly in volume. As a rule, it includes:
- Personal data of the individual (full name, date and place of birth, citizenship);
- Description of appearance and distinguishing features;
- Information about a criminal case or alleged crime;
- Data on the national arrest warrant (if available);
- Formulation of a request to other states;
- Contacts of the competent authority.
A fundamental feature is that diffusions are not publicly accessible. They are not published on the official Interpol website, do not appear in open databases, and are not automatically disclosed to the individual. Information about such a request is available only to law enforcement agencies of recipient countries through a closed communication system.
We confirm whether an Interpol diffusion exists, without exposing your location, and assess it for Article 3 violations. Act before a border check or bank review does it for you.
Check my status confidentiallyTypes of Interpol Notices
Interpol uses a system of color-coded notices for standardized information exchange between law enforcement agencies of different countries. Each color represents a specific legal purpose of the request and the nature of international cooperation:
Red Notice
Used for the search of a person with the purpose of temporary detention and subsequent extradition or a similar legal procedure.
Blue Notice
Issued to identify a person, determine their whereabouts, or obtain additional information about a person of interest in an investigation.
Green Notice
Warns other countries about an individual who has previously committed crimes and may pose a potential threat.
Yellow Notice
Used for the search of missing persons, including minors, or to establish the identity of unknown individuals.
Black Notice
Used to obtain information about unidentified bodies.
Purple Notice
It is used for the exchange of information about methods of committing crimes, objects used, technical means, and schemes.
Orange Notice
Warns of potential threats to public safety, including dangerous items, substances, or methods of their use.
Silver Notice
Intended for the exchange of information about individuals of interest to national law enforcement agencies for administrative or migration purposes.
UN Security Council Special Notice
Related to individuals and organizations subject to UN Security Council sanctions regimes.
The difference between Diffusion and Red Notice
In international search practice, two Interpol tools are most commonly used — Red Notice and Diffusion. Both mechanisms are applied for locating individuals and can lead to detention; however, their legal nature, processing procedure, and level of control differ significantly.
| Criterion | Red Notice | Diffusion |
|---|---|---|
| Legal nature | Formalized notification of Interpol | Informal operational request between countries |
| Who initiates | The National Bureau of Interpol through the General Secretariat | The National Bureau of Interpol directly to other states |
| Interpol review | Yes, by the NDTF before publication | No approval before sending; compliance review by the NDTF afterwards |
| Speed of propagation | Relatively slow (requires review) | Very high, can spread within hours |
| Publicity | Sometimes published on the Interpol website | Never published in open access |
| Awareness of the wanted person | In certain cases, it is possible to find out in advance. | It usually becomes known only during detention or inspection. |
| Risk of abuse | Below due to preliminary control | Higher due to the lack of primary filtration |
| Possibility of detention | Yes | Yes |
| Extradition consequences | Possible | Possible |
| Practical effect | International search | International search |
Despite its less formalized nature, diffusion poses a greater danger to an individual, as it is used without public notification, applied significantly faster, and can be directed with a limited evidentiary basis. At the same time, for border and law enforcement agencies in most countries, the consequences of diffusion and a Red Notice are practically identical: both tools can serve as grounds for detention and the initiation of extradition procedures.
Red Diffusion vs Other Types of Diffusion
“Red diffusion” is the common name for a Wanted Person Diffusion: a request to arrest or locate a person with a view to extradition. It is not the same as a Red Notice, although the practical effect at a border is similar. Interpol diffusions also exist for other purposes: locating missing persons, identifying unknown persons, or warning about dangerous individuals or methods. A diffusion is sometimes wrongly called a “diffusion notice”. Legally it is a request sent by a member country, not a notice issued by Interpol.
When Is a Wanted Person Diffusion Non-Compliant or Prohibited?
A Red Notice or Wanted Person Diffusion is non-compliant when it targets a person in breach of Interpol’s rules. Typical grounds:
- Political, military, religious or racial character (Article 3 of Interpol’s Constitution), including cases of persecution of opponents, journalists or businesspeople;
- Conflict with human rights standards (Article 2 of the Constitution);
- Civil, commercial or family disputes presented as criminal cases;
- Insufficient or inaccurate data, such as no link to a criminal case or no valid national warrant;
- Disproportionate or expired charges, including an expired statute of limitations;
- Circumvention of a refused Red Notice: a diffusion sent after the General Secretariat has already refused a Red Notice for the same person. The CCF treats this as a serious breach.
These are the strongest grounds to fight an Interpol diffusion before the CCF. Send us the basics and our lawyers will tell you what the case supports.
Get a case assessmentRisks for UAE residents
The status of a UAE resident does not protect against the consequences of an international search, diffusions, or Interpol notices. On the contrary, strict compliance rules, a developed banking system, and active cooperation with foreign authorities make the Emirates a jurisdiction with a high level of practical law enforcement. For foreigners, such requests often entail not only criminal-legal but also serious migration and financial consequences.
Banks in the UAE operate under strict AML/CTF control and automatically respond to mentions of being wanted or Interpol requests. Diffusion or Red Notice can lead to account freezes, suspension of operations, and refusal of transfers even without a local court decision. Unblocking usually requires official clarifications and can take a long time.
Information about international search can enter migration systems through Interpol or directly from foreign authorities. This often leads to visa extension refusals, cancellation of Emirates ID, or the inability to change visa status. Loss of documents essentially means the risk of being forced to leave the country.
Active diffusion or Red Notice can serve as grounds for temporary detention in the UAE. After this, the issue of extradition is considered by the court based on international treaties. Although extradition is not automatic, the procedure is often accompanied by detention and serious restrictions on freedom.
In addition to measures from banks and migration authorities, residents often face service refusals, contract terminations, difficulties in business registration, and increased regulatory oversight. Collectively, this can paralyze entrepreneurial activity and make further residence in the UAE extremely challenging.
How to find out about the presence of Diffusion?
A diffusion is not published and the wanted person is not notified. It usually surfaces during a border check, a bank compliance review or a visa procedure. Border officers can also see data on documents linked to notices and diffusions through Interpol’s systems such as TDAWN (Travel Documents Associated with Notices).
The fact of the presence of information about a person in the Interpol system can only be established through an appeal to the Commission for the Control of Interpol’s Files. CCF is authorized to:
- Confirm the presence or absence of information about a person in Interpol databases;
- Evaluate the legality of personal data processing;
- Consider requests for the removal or correction of information.
The procedure is carried out in written form and takes several months.
Despite the formal availability of the procedure, applying to the CCF without legal training may entail additional risks:
- Disclosure of the actual location and current contact details;
- Confirmation that the person is active and available for procedural actions;
- Errors in wording that complicate further appeals;
- The absence of a coordinated defense strategy when confirming the search.
In some cases, a careless request can accelerate the actions of the law enforcement agencies of the initiating country.
The role of a lawyer
Dr. Anatoliy Yarovyi specializes in cases related to international search, diffusions, and Interpol notices, including instances involving UAE residents. In his practice, he uses the preventive request mechanism in the CCF Commission, which allows verifying the presence of information about a client without directly disclosing their actual location and without provoking law enforcement agencies. This approach reduces the risk of sudden arrests, account freezes, and visa status issues.
In addition to checking the status, Anatoliy Yarovyi analyzes the legality of the request, identifies violations of Interpol rules, and prepares a legal position for possible appeals or data removal. He also coordinates client protection in interactions with banks, migration authorities, and, if necessary, with the National Central Bureau of Interpol in the UAE. Under conditions of high compliance pressure and active international cooperation, such professional legal support allows minimizing risks and maintaining control over the situation.
A careless request can disclose your location and speed up action by the sending country. We file a preventive CCF request and plan the strategy before anything is submitted.
Speak to an Interpol lawyerProcedure for removal
Stage 1. Confirming the diffusion and mapping its content.
We establish which state sent the request, which charges or national warrant it relies on, and whether it was recorded in Interpol’s databases. Every later stage depends on this.
Stage 2. Legal analysis for compliance with the Constitution of Interpol
The key stage is to verify whether the diffusion complies with the provisions of the Interpol Constitution and the organization’s Rules on the Processing of Data. Identified violations form the basis for a subsequent request for data deletion.
Stage 3. Formation of the legal strategy
After analyzing the materials, a defense strategy is developed taking into account the jurisdiction of the UAE and the country initiating the request. The objectives of the procedure are determined: complete removal of diffusion, limitation of its effect, or correction of inaccurate data. Associated risks and the necessity of parallel actions in national authorities are also assessed.
Stage 4. Preparation and submission of a request for removal
The main procedural step is the submission of an official deletion request to the CCF Commission. The request is submitted in written form and must include a legal justification for violations of Interpol’s rules, references to the norms of Interpol’s Constitution and internal regulations, as well as arguments regarding the disproportionality or illegality of data processing. Incompleteness or inaccuracies in wording can significantly reduce the chances of success.
Stage 5. Consideration of the CCF case and interaction with Interpol
CCF requests explanations from the state that initiated the diffusion and conducts an independent legal assessment. The procedure can take from several months to a year, depending on the complexity of the case and the activity of the parties. In certain cases, the commission requests additional documents or clarifications.
Stage 6. Implementation of the solution and consequences for status in the UAE
In case the request is satisfied, the diffusion is removed from Interpol’s information systems, and corresponding notifications are sent to the national bureau. This allows initiating the unblocking of bank accounts, restoration of visa status, and elimination of restrictions that arose in the UAE. If removal is denied, it is possible to submit additional materials or adjust the defense strategy.
Grounds for Removal — What’s Different for a Diffusion
The legal grounds for challenging a Diffusion are the same core standards the CCF applies to any Interpol record — Article 3 violations, inaccurate data, disproportionality, expired statute of limitations. (See our CCF guide for the full breakdown of these standards.)
What is specific to a diffusion is that Interpol does not approve it before sending. Diffusions are therefore more often used for civil, commercial or family-dispute pressure, which Article 3 prohibits, and for pressure on persons whose Red Notice was refused. This is the strongest argument when you fight an Interpol diffusion before the CCF.

Our team has been assisting clients for many years in procedures of verification, appeal, and removal of diffusions and Interpol notices. We have practical experience in interacting with the CCF, including the preparation of preventive requests and deletion requests, taking into account the current practices of the commission and the requirements for the evidence base.
Particular attention is paid to the protection of clients residing or conducting business in the UAE, where international Interpol requests are quickly integrated into banking and migration systems. We take into account the specifics of the work of local banks, migration authorities, and the National Central Bureau of Interpol in the Emirates.
Anatoliy Yarovyi personally oversees the development of a defense strategy for each case related to Interpol diffusions. His practice includes analyzing the compliance of requests with the Interpol Constitution, assessing extradition risks, and building a comprehensive legal position for the CCF and national authorities. This approach allows not only achieving the removal of unlawful data but also minimizing the accompanying financial and migration consequences for the client.
Faced with the risk of extradition?
The risk of extradition can arise suddenly: when crossing the border, renewing a visa, during a bank check, or after the issuance of a diffusion or an Interpol Red Notice. It is important to understand that extradition is not an automatic procedure; however, without timely legal protection, it can be carried out in a short time and with serious consequences for the individual and their family.
Our legal team provides comprehensive assistance in cases related to extradition and international search: from urgent legal assessment of the situation to developing a defense strategy in national courts and interacting with Interpol. If you are facing the threat of extradition or suspect the existence of an international request, contact us as soon as possible – this will allow you to protect your rights and maintain control over the situation.
Removal of the diffusion is the route to unblocking accounts and restoring visa status. Our team runs the CCF removal and the steps with banks and migration authorities in parallel.
Start removal of the diffusionFAQ
What is the difference between an Interpol Diffusion and a Red Notice?
A Diffusion is sent directly by one country’s National Central Bureau to other countries without prior approval from Interpol’s General Secretariat. A Red Notice is requested through the General Secretariat and reviewed by the NDTF before publication. Both can lead to detention at a border or airport, but a Diffusion is never published and often becomes known only during a check.
Can an Interpol Diffusion be removed, and how long does the process take?
Yes. Diffusions can be challenged before the CCF on the same grounds as Red Notices. The CCF reviews the request, asks the sending country for its position, and can order the data deleted. It usually takes several months and can exceed a year in complex cases. Where a diffusion causes problems in the UAE, parallel steps with banks and migration authorities are possible.
How do I fight an Interpol diffusion?
First confirm that a diffusion exists and which country sent it. Then assess whether it breaches Articles 2 or 3 of the Constitution or the Rules on the Processing of Data, and file a reasoned request with the CCF. Filing without a strategy can reveal your location, so get legal advice first.
What is a red diffusion?
“Red diffusion” is the common name for a Wanted Person Diffusion, a request to arrest or locate a person pending extradition. It carries no force of a court order, but countries may act on it.
Can a diffusion cause an arrest in the UAE?
Yes. A diffusion can lead to temporary detention. Extradition is then decided by a court under treaties or the principle of reciprocity, and is not automatic.
