A man wielding a sword went on a stabbing spree in London on Tuesday, killing a 14-year-old boy and wounding four people, before being tasered and arrested by a woman police officer.
A video going viral on social media platforms showed the moment the police tasered and arrested the 36-year-old suspect near Hainault in east London.
The dramatic 22-second footage shows the woman officer approaching the suspect in a street as he tries to run away.
As he turns away from the officer, she immediately uses taser discharges to bring him to the ground.
A few seconds later, six officers can also be seen moving towards the suspect, who was then pinned down and arrested.
The police said that he had been arrested on suspicion of murder and was currently in hospital, having suffered injuries when his van collided with a building before the stabbing incident.
