PARIS — French prosecutors raided the offices of social media platform X on Tuesday as part of a preliminary investigation into allegations that include spreading child sexual abuse images and deepfakes. They have also summoned billionaire owner Elon Musk for questioning.

X and Musk’s artificial intelligence company xAI also face intensifying scrutiny from Britain’s data privacy regulator.

Grok, Musk’s artificial intelligence chatbot which was built by xAI and is available through X, sparked global outrage last month after it pumped out a torrent of sexualized nonconsensual deepfake images in response to requests from X users.

The French investigation was opened in January last year by the prosecutors’ cybercrime unit, the Paris prosecutors’ office said in a statement. It’s looking into alleged “complicity” in possessing and spreading pornographic images of minors, sexually explicit deepfakes, denial of crimes against humanity and manipulation of an automated data processing system as part of an organized group, among other charges.
