MOSCOW, April 22 (Reuters) - Pavel Durov, the founder of the Telegram messenger app, said on Wednesday he had received a summons in Russia at an old address naming him as a "suspect" in a criminal case.
Russia stepped up its bid to subjugate Telegram in February, announcing in a state-run newspaper it was investigating billionaire founder Durov as part of a criminal case involving accusations of terrorism.
