French prosecutors raided X’s Paris offices as part of a criminal investigation led by the Paris prosecutor’s cybercrime unit with support from France’s National Gendarmerie and Europol. Authorities said the probe—opened in January 2025 after complaints from French officials—covers allegations including fraudulent/automated data extraction, tampering with automated data processing systems, and potential organized manipulation of X’s recommendation algorithms, including concerns about possible influence by foreign actors. Prosecutors also summoned Elon Musk and X executive Linda Yaccarino for voluntary interviews in Paris in April, and called additional employees as witnesses; no charges or arrests were reported at the time of the search.
The investigation expanded to include X’s AI chatbot Grok, following complaints that it facilitated or generated illegal content, including sexually explicit deepfakes (including alleged depictions of minors), Holocaust denial content, and alleged complicity in the possession/distribution of child sexual abuse material (CSAM), alongside allegations of operating an illicit online platform. UK regulators also opened parallel scrutiny: the ICO launched a formal investigation into X and Grok over potential generation of nonconsensual sexualized images (including of children), and Ofcom had previously announced its own inquiry into related concerns. Separately, European policy pressure on youth social media access continued, with the Netherlands considering a higher minimum age and stricter platform oversight, but that debate is distinct from the French criminal case.

On February 3, 2026, French prosecutors and police searched X's Paris offices as part of the ongoing criminal investigation into illegal content, data-related offenses, and alleged platform misuse. The operation involved France's cybercrime authorities and Europol, and no arrests were reported.
UK authorities, including the ICO and Ofcom, opened investigations into X and Grok over the generation of nonconsensual sexualized images, including images involving children. The inquiries focused on lawful personal-data processing and whether adequate safeguards were in place.
In July 2025, French authorities expanded the X investigation after reports that Grok was used to disseminate sexually explicit deepfakes and Holocaust-denial content. The broadened probe also came to examine allegations tied to child sexual abuse material and other illegal content on the platform.
The Paris prosecutor's office opened a criminal investigation into X in January 2025 following complaints alleging offenses including fraudulent data extraction, platform misuse, and disruption of automated data-processing systems.
