A member of the Russian protest group Pussy Riot said Tuesday he’s recovering after two weeks in intensive care for a suspected poisoning.

German doctors treating Pyotr Verzilov, a member of Russian protest group Pussy Riot, said Tuesday that claims he was poisoned are "highly plausible" but stressed they can't say how this might have occurred or who was responsible.

Pyotr Verzilov arrived in Berlin from Moscow late on Saturday on a medical transport plane, according to the human rights group Cinema for Peace.
