Elon Musk’s X offices in Paris were searched by French police on Tuesday, and prosecutors summoned the tech billionaire to appear for questioning in April as part of an investigation into the alleged distribution of sexually explicit deepfakes and Holocaust denial content, NBC News reported. Employees of the French prosecutor’s cybercrime unit, together with the French police’s own cybercrime unit and Europol, the EU’s central law enforcement agency, are conducting the search.

According to NBC, prosecutors want Musk and former X CEO Linda Yaccarino, who resigned in July 2025, to appear for questioning the week of April 20.

A representative for X did not immediately respond to a request for comment.

“Voluntary interviews with managers should enable them to explain their position on the facts and, if possible, the compliance measures planned,” the prosecutor’s office said in a statement.

According to the report, prosecutors are investigating possible links to the possession and distribution of child pornography images and the creation of sexual deepfakes. Prosecutors said they were also investigating the alleged denial of “crimes against humanity” and the fraudulent extraction of data from an automated processing system.

Deepfakes are falsified videos which shows that someone did or said something that they did not do.

Also on Tuesday, Reuters reported that the UK’s Information Commissioner’s Office — an independent watchdog designed to ensure data privacy and enforce data protection laws — launched an investigation into the xAI chatbot Grok following reports that it was being used to create sexual images of individuals, including children, without consent.

Grok is a free-to-use chatbot created by xAI, an artificial intelligence company founded by Musk in 2023. Like ChatGPT and Google Gemini, Grok is designed to answer people’s questions, help with tasks, create and summarize content, and perform other functions. But in January, the chatbot made global headlines and sparked outrage after it was widely used to create non-consensual sexual images of real people, including minors, in threads on Musk’s social-media platform, X.

“At this stage, the conduct of this investigation is part of a constructive approach, with the aim of finally ensuring that the X platform complies with French laws, when it operates on national territory,” the Paris prosecutor’s office said.

The raid in Paris and the new investigation in the UK stem from an investigation launched last week by the European Union, which will try to determine whether X is spreading illegal content – also prompted by accusations that people have made sexual images of Grok.

Several other countries have acted amid complaints about Grok. Indonesia and Malaysia Grok was temporarily banned before the restrictions were lifted. Brazil issued an ultimatum to Grok to stop the circulation of sexual content. Australian politicians chatbot is condemned. and Canada and India an investigation has begun.
