Elon Musk has been summoned to Paris, where investigators are looking into allegations of misconduct related to the social media platform X, including the spread of child sexual abuse material and deepfake content.

The world’s richest man and Linda Yaccarino – the former chief executive of X – were on Monday summoned for “voluntary interviews”, while other employees of the platform were scheduled to be heard as witnesses throughout this week, the Paris prosecutor’s office said.

It remains unclear whether Musk and Yaccarino will travel to Paris. A spokesperson for X did not respond to questions from Associated Press and Yaccarino’s current company, eMed, did not answer a request sent to the press email.
