Alexei Navalny was brought home from the police station, he wrote on his Twitter. “They took Arbat out of the police department through some kind of back door, put me in a car and brought me home. At the entrance, naturally, some kind of acceptance certificate was drawn up from the Ministry of Internal Affairs to the Federal Penitentiary Service. Funny. The protocol of detention and all that, of course, was not drawn up. They say “let's consider this a preventive conversation,” said Alexei Navalny.
