France extends detention of Telegram founder Durov

French judicial authorities have extended the detention of the Russian-born founder and chief of Telegram, Pavel Durov, after his arrest at a Paris airport over alleged offences related to the popular messaging app.

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 then decide to free him or press charges and remand in further custody.

Russia has accused France of "refusing to cooperate" and fellow tech mogul Elon Musk swept to his defence.

Durov holds a French passport in addition to other nationalities. Durov had arrived in Paris from Baku, Azerbaijan, and was planning to have dinner in the French capital, a source close to the case said.

He was accompanied by a bodyguard and a personal assistant who always accompanied him, added the source, asking not to be named.

France's OFMIN, an office tasked with preventing violence against minors, had issued an arrest warrant for Durov in a preliminary investigation into alleged offences, including fraud, drug trafficking, cyberbullying, organised crime and promotion of terrorism, another source said.

Durov is accused of failing to take action to curb the criminal use of his platform.

Telegram said in response that "Durov has nothing to hide and travels frequently in Europe."

"Telegram abides by EU laws, including the Digital Services Act -- its moderation is within industry standards," it added.

"It is absurd to claim that a platform or its owner are responsible for abuse of that platform."

'Assault on basic human rights'

Durov founded Telegram in 2013 after his first project, the Russian social network VKontakte (VK), ran into ownership difficulties he blamed on the Kremlin.

Telegram has become hugely popular partly due to the ease of viewing and posting videos on its messaging "channels."

But critics accuse it of often hosting illegal content, including disinformation and services for buying drugs.

Russia's embassy to Paris said it had demanded access to Durov but had had no response from France, saying "the French side is refusing to cooperate.".

Russian foreign ministry spokeswoman Maria Zakharova said Moscow had asked for consular access, but since Durov also had French citizenship, "France considers that it is his main nationality."

Musk, who leads the Tesla car group and the X social media, formerly Twitter, posted the hashtag #FreePavel on X and commented in French, "Liberte Liberte! Liberte?" (Freedom Freedom! Freedom?).

US whistleblower Edward Snowden, who took asylum in Russia, blasted "an assault on the basic human rights of speech and association", saying he was saddened Paris had "descended to the level of taking hostages as a means for gaining access to private communications."

'Independence, privacy, freedom'

A source close to the case expressed surprise that Durov had flown to France with a warrant against him. "Perhaps he had a feeling of impunity," said the source.

Telegram, an encrypted messaging app based in Dubai, has positioned itself as an alternative to US-owned platforms, which have been criticised for their commercial exploitation of users' personal data.

Telegram has committed to never disclosing information about its users.

People "love the independence. They also love the privacy, the freedom, (there are) a lot of reasons why somebody would switch to Telegram," Durov told Tucker Carlson in an interview.

He said at the time that the platform had more than 900 million active users.

Telegram allows groups of up to 200,000 members, which has led to accusations that it makes it easier for false information to spread virally.

Competitor messaging service WhatsApp introduced worldwide limits on message forwarding in 2019 after it was accused of enabling the spread of false information in India that led to lynchings.
