The Globe and Mail reports in its Wednesday edition that French police raided the offices of Elon Musk's social-media network X on Tuesday and prosecutors ordered the tech billionaire to face questions in a widening investigation. A Reuters dispatch to The Globe says the raid by the Paris prosecutor's cybercrime unit and Mr. Musk's summoning are linked to a year-long investigation into suspected abuse of algorithms and fraudulent data extraction by X or its executives. The United Kingdom's privacy watchdog, meanwhile, also kicked off a formal investigation into Mr. Musk's artificial-intelligence chatbot Grok over the processing of personal data and its potential to produce harmful sexualized images and video content. Referring to the raids, Mr. Musk said in a post on X, "This is a political attack." The Paris prosecutor's office said it had broadened the scope of its investigation following complaints over the functioning of Grok. The French probe will now also investigate alleged complicity in the "detention and diffusion" of images of a child-pornographic nature and the violation of a person's image rights with sexually explicit deepfakes, among other potential crimes. Mr. Musk was summoned to a hearing on April 20.
