Screen-grab from a video showing a youth slapping an elderly woman on Hounslow High Street, London, Monday 5th February, 2018. A SHOCKING video has surfaced online showing a schoolgirl SLAP an elderly woman on a busy street in Hounslow, West London. In the horrifying clip, the teenager shouts at the old lady before forcibly hitting her across the face to screams from the crowds and the victim shaken in tears. The incident took place in Hounslow High Street three days ago. The appalling video was published on Snapchat by a user called Skye and has since been shared on Instagram. The video starts with the teenage girl - who is wearing a school uniform à shouting ÒWho you talking to?Ó to the elderly woman in the middle of a busy high street. The clip appears to be being filmed on a mobile phone by a passer-by. Three male teenagers in school uniform can also be seen watching the tense exchange and there seems to be other onlookers behind the camera. The schoolgirl once again gesticulates and yells ÒWho you talking to?Ó to the old lady who is carrying shopping bags. The woman gently shakes her head and appears to quietly speak to the girl. However her words cannot be heard on the video. But as the elderly female continues to speak imperceptibly, the teenager suddenly slaps the victim violently across the face with her left hand. The assailant then walks backwards away from the scene. The shocking act is immediately met with piercing shrieks from the crowds and the old woman clutches her face in disbelief. She appears visibly shaken and begins to cry in pain. Onlookers can be heard condemning the violence in the video. One bystander shouts ÒNo! Oh my GodÓ whilst another spectator laments ÒNot on her face!Ó. Meanwhile another witness laments ÒNo! What you doing man?Ó As the elderly woman sobs, a passer-by from the other side of the street comes to her aid and puts a comforting arm around the victim. The video then cuts to a close.
