PARIS, Aug 24 (Reuters) – Pavel Durov, the Russian-French billionaire founder and CEO of the Telegram messaging app, was arrested at Bourget airport outside Paris on Saturday evening, TF1 TV and BFM TV said, citing unidentified sources.
Durov was travelling aboard his private jet, TF1 said on its website, adding he had been targeted by an arrest warrant in France as part of a preliminary police investigation.
TF1 and BFM both said the investigation was focused on a lack of moderators on Telegram, and that police considered that this situation allowed criminal activity to go on undeterred on the messaging app.
Durov faces possible indictment on Sunday, according to French media.
The encrypted Telegram, with close to one billion users, is particularly influential in Russia, Ukraine and the republics of the former Soviet Union. It is ranked as one of the major social media platforms after Facebook, YouTube, WhatsApp, Instagram, TikTok and Wechat.
Telegram did not immediately respond to a Reuters request for comment. The French Interior Ministry and police had no comment.
