The arrest of Telegram’s founder rattles social media

Soon after his private jet touched down on August 24th at Le Bourget airport, on the outskirts of Paris, Pavel Durov was arrested by French police. A statement later released by prosecutors said that the 39-year-old billionaire had been detained as part of an investigation into Telegram, the social-media app of which he is the founder and chief executive. French judges have until August 28th to decide whether to pursue charges or release him.
