This is in St. Petersburg. How can we find this bastard warrant officer? Update. As was very rightly pointed out in the comments, this is apparently the guy who was hit in the face with a baton and was stopping dacha-goers from getting to their summer homes. Update 2.
Most likely, this brave man is a warrant officer from military unit 5402 of the Internal Troops of the Russian Ministry of Internal Affairs. Location of the incident: 35 Nevsky Prospekt. There is a witness ready to testify: il**ya_evseev **The injured man is also being sought.
