A coordinated police operation across 19 countries led by Danish authorities arrested 25 people for distributing AI-generated images depicting child sexual abuse through an online platform.

What happened
Authorities in 19 countries conducted a coordinated operation known as Operation Cumberland against a criminal network distributing AI-generated images depicting child sexual abuse. The Danish-led operation resulted in 25 arrests, with the primary suspect being a Danish citizen arrested in November 2024 who operated an online platform distributing AI-generated material.
The platform allowed users worldwide to access the content after making symbolic payments. During the operation conducted on 26 February 2025, authorities identified 273 suspects, conducted 33 house searches, and seized 173 devices. In Hungary, searches were carried out at addresses of two Hungarian citizens who had purchased access to the content created by the Danish suspect.
Reported impact
Europol noted that AI-generated child sexual abuse material contributes to the objectification and sexualization of children. The material is also used for extortion purposes, and the increasing sophistication of AI makes distinguishing between synthetic and genuine content increasingly difficult.
The operation revealed that many countries lack adequate legislation to address AI-generated child sexual abuse material, presenting significant challenges for investigators.
Index analysis
This operation represents one of the first cases in which authorities took action against AI-generated child sexual abuse material. Europol stated that online sexual exploitation of children remains one of the most threatening manifestations of cybercrime in the EU.
Europol emphasized that developed legislation and improved law enforcement tools are necessary to address this emerging threat, and announced plans for an online campaign targeting potential offenders to warn them of criminal consequences.
Governance controls
The European Commission is currently discussing a common regulatory proposal with EU member states aimed at strengthening protection against child sexual exploitation. Europol called for the development of legislation and law enforcement tools to counter AI-generated child sexual abuse material.
