An eyewitness has described the moment he saw police taser and arrest a man armed with a sword after a 14-year-old boy was killed and two police officers seriously injured in an attack in London on Tuesday (30 April). A further four people were also wounded in the terrifying attack in Hainault, east London. Eyewitness Chris Bates told Sky News: “They (the police) all ran up to where he was in the driveway shouting and screaming for him to put the sword down. “He had a big samurai sword and they were screaming at him. “They tasered him and seven or eight of them piled on top of him.” A 36-year-old man remains in custody.
