In 2014, Pavel Durov fled the country after allies of the Kremlin took control of the social networking site most know just as VK.

Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. Russians and Ukrainians are both prolific users of Telegram.
