Messaging app Telegram has said its CEO Pavel Durov, who was detained in France on Saturday, has “nothing to hide”.

Mr Durov was arrested at an airport north of Paris under a warrant for offences related to the app, according to officials.

The investigation is reportedly about insufficient moderation, with Mr Durov accused of failing to take steps to curb criminal uses of Telegram. The app is accused of failure to co-operate with law enforcement over drug trafficking, child sexual content and fraud.

Telegram said in a statement that “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,” the app said.
