Magomed Jangubaev (Магомед Янгубаев) is a Russian/Chechen boxer currently living in Germany. He’s had some boxing accomplishments, but nothing that would make him a recognizable name.
This video captures a bloodied man who’s already had enough, receiving vicious beating despite having already been rendered defenseless. The attacker, allegedly is the above mentioned boxer Magomed Jangubaev (sometimes his name is spelled Magomed Yangubaev), the victim is alleged to have been involved in murder.
