PARIS -- The Paris prosecutor's office said on Tuesday that the French offices of social media platform X were being searched as part of an investigation.

The prosecutor's cybercrime unit is conducting the searches with the support of Europol and the cyber unit of the National Gendarmerie, it said in a post on X, adding that the action is related to an investigation opened in January 2025.

The investigation was launched after a French lawmaker contacted prosecutors over concerns about allegedly biased algorithms on the X platform, France Info reported.

Citing a statement from the Paris prosecutor's office, France Info said the scope of the investigation was later expanded following additional complaints alleging that the operation of Grok on X had led to the dissemination of Holocaust-denying content and sexually explicit deepfake videos.

X's owner Elon Musk and former CEO Linda Yaccarino have been summoned to a hearing on April 20, with other X staff also summoned as witnesses, said the report.

As a result of the procedure, the Paris prosecutor's office said it would leave X and direct the public to its other social media accounts.
