French judicial authorities on Sunday extended the detention of the Russian-born founder of Telegram, Pavel Durov, after his arrest at a Paris airport over alleged offences related to the messaging app, writes The Guardian.

His arrest at the Le Bourget airport outside Paris on Saturday was the latest extraordinary twist in the career of one of the world’s most influential tech icons.

The detention of Durov, 39, was extended beyond Sunday night by the investigating magistrate who is handling the case, according to a source close to the investigation. This initial period of detention for questioning can last up to a maximum of 96 hours.

When this phase of detention ends, the judge can decide to free him or press charges and remand in further custody.

French investigators had issued a warrant for Durov’s arrest as part of an inquiry into allegations of fraud, drug trafficking, organised crime, promotion of terrorism and cyberbullying.

Durov is accused of failing to take action to curb the criminal use of his platform and was stopped after arriving in Paris from Baku on his private jet on Saturday night. “Enough of Telegram’s impunity,” said one investigator who expressed surprise that Durov flew to Paris knowing he was a wanted man.
