In a shocking video, a young woman was at the receiving end when her boyfriend knocked her down after a heated argument. The macho man’s fury did not abate with that as he went on to assault a female passer-by who tried to help the woman. He also tried to snatch her mobile phone fearing she had captured the attack on her mobile device. The video, which has gone viral on the social media, was captured from the window of a nearby building in the central Raussian city of Yekaterinburg, in the Sverdlovsk Oblast region.
