Paris. French President Emmanuel Macron said Monday that the arrest in France of the CEO of the popular messaging app Telegram, Pavel Durov, wasn't a political move but part of an independent investigation.

Durov was detained Saturday at Le Bourget airport in a judicial inquiry opened last month involving 12 alleged criminal violations, the Paris prosecutor's office said Monday.

It said in a statement that the suspected violations include complicity in selling child pornography and in drug trafficking, fraud, abetting organized crime transactions, and refusing to share information or documents with investigators when required by law.

In France's first public comment on the arrest, Macron posted on the social media platform X that his country "is deeply committed" to freedom of expression but "freedoms are upheld within a legal framework, both on social media and in real life, to protect citizens and respect their fundamental rights."

Denouncing what he called false information, Macron said the arrest "is in no way a political decision. It is up to the judges to rule on the matter."

Durov's detention was extended until Monday night and can be prolonged until Wednesday evening before authorities must release or charge him, the prosecutor's office said.

Durov is a citizen of Russia, France, the United Arab Emirates, and the Caribbean island nation of St. Kitts and Nevis.

Russian government officials have expressed outrage at his detention, with some calling it politically motivated and proof of the West's double standard on freedom of speech. The outcry has raised eyebrows among Kremlin critics: in 2018 Russian authorities themselves tried to block Telegram but failed, withdrawing the ban in 2020.

Telegram, which says it has nearly a billion users worldwide, was founded by Durov and his brother after Durov faced pressure from the Russian authorities.

In 2013, he sold his stake in VKontakte, a popular Russian social networking site that he launched in 2006.

The company came under pressure amid the Russian government's crackdown after mass pro-democracy protests that rocked Moscow at the end of 2011 and 2012.

Durov said the authorities demanded that the site take down online communities of Russian opposition activists, and later that it hand over personal data of users who took part in the 2013 popular uprising in Ukraine, which eventually ousted a pro-Kremlin president.

Durov said in a recent interview that he had turned down these demands and left the country.

The demonstrations prompted Russian authorities to clamp down on the digital space, and Telegram and its pro-privacy rhetoric offered a convenient way for Russians to communicate and share news.

Telegram also continues to be a popular source of news in Ukraine, where both media outlets and officials use it to share information on the war and deliver missile and air raid alerts.

In a statement posted on its platform after his arrest, Telegram said it abides by EU laws, and its moderation is "within industry standards and constantly improving."

"It is absurd to claim that a platform or its owner are responsible for abuse of that platform," Telegram's post said. "Almost a billion users globally use Telegram as means of communication and as a source of vital information. We're awaiting a prompt resolution of this situation. Telegram is with you all."

Elon Musk, the billionaire owner of X who has in the past called himself a " free speech absolutist," posted "#freePavel" in support of Durov following the arrest.
