INTERPOL UPDATE: City of London Police secure INTERPOL Silver Notice against convicted fraudster

We have been tracking closely the increased use of the INTERPOL Silver Notice.

This includes INTERPOL’s collaboration with Indian law enforcement to enhance international cooperation, collaboration with African law enforcement to disrupt criminal activity by way of the INTERPOL Silver Notice, as well as the INTERPOL Silver Notice featuring on the agenda at the latest European Regional Conference.

Since its inception in January 2025, the use of the Silver Notice has grown exponentially.

By the end of June 2025, INTERPOL reported over 50 published Silver Notices worldwide.

Why did the City of London Police apply for a Silver Notice?

The City of London Police have successfully secured an INTERPOL Silver Notice to assist them with the tracing and recovery of assets belonging to convicted fraudster Anthony Constantinou.

The application for the Silver Notice was made as part of an extensive operation in relation to a company which falsely promised investors annual returns of 60% on what it claimed were risk-free foreign exchange investments.

The Silver Notice was requested by the City of London Police on the basis of intelligence suggesting that Mr Constantinou held assets in multiple foreign jurisdictions.

What is the Silver Notice used for?

A Silver Notice is used to “track the offenders, terrorist financers and others who are using virtual currencies like bitcoin to move and store illicit funds, out of the reach of law enforcement and other authorities”:

What is INTERPOL’s Silver Notice?

In January 2025, we wrote an article explaining how INTERPOL had published its first-ever Silver Notice:

INTERPOL publishes its first-ever Silver Notice to trace criminal assets

What assets does the Silver Notice target?

The Silver Notice targets assets that constitute the illegal proceeds of criminal activities, such as fraud, corruption, drugs, arms and human trafficking and environmental crime. These assets may range from cryptocurrency or cash to real estate and luxury items (such as yachts or cars).

What is the purpose of the Silver Notice?

The purpose of the Silver Notice is to target international criminals’ financial gains, and by doing so, “to disrupt criminal networks and reduce their harmful impact on communities worldwide”.
