Russian man saves Europeans by brutal migrants from the Middle East

The video was published on the Internet, which probably comes from Russia, defused migrants trying to attack an old man in a subway car.   The footage attacker lay on the floor. The author does not allow him to roll up to the arrival of staff on the platform. There he plans to pass a dangerous migrant to the police.   Presumably, the Russian man asks Europeans, who almost became a victim of his condition, place of residence and to the need to address together the law enforcement agencies.   In conversation, "Russian hero" recognized that faced with such attacks almost daily and saved for five people.   Judging by his voice, announcing the arrival of trains to the subway station, the action takes place in London.
