Telegram founder and CEO Pavel Durov was arrested at the Bourget airport near Paris on Saturday, according to French outlet TF1, which cited an unnamed source.  

The Daily Mail reported that Durov had been traveling on his private jet and was targeted by an arrest warrant in France, according to the French outlet. He was reportedly arrested around 8 pm local time when he was with his bodyguard.  

Durov founded Telegram in 2013 along with his brother. The messaging service has 950 million users worldwide and is seen as an uncensored free speech platform. Durov is originally from Russia, but has not lived there since Vladimir Putin's invasion of Crimea. In 2014 he said, "I don't have any business in Russia and have no plans to return there. I have no Russian citizenship anymore." The tech tycoon lives in Dubai and has dual citizenship in both France and the United Arab Emirates. 

Durov said earlier this year that Telegram would remain as a “neutral platform” and not a “player in geopolitics.” However, the UK government has taken issue with Telegram, saying that it allows extremists to use it for criminal means.  

The platform offers end-to-end encryption, meaning data can only be accessed by the users. It has calls as well as "secret chats" that focus on the privacy aspect of the platform. 

The Telegram founder and CEO is estimated to be worth about $15.5 billion, per Reuters. When the outlet reached out to the French Interior Ministry and law enforcement for comment, neither immediately responded on the matter.
