Dramatic footage shot from a police helicopter shows the moment an acid attacker was arrested in north London, after entering a park and attempting to hide from officers.

In the video the attacker, Derryck John, lies down, before standing and running out of the park where an officer tackles him to the ground as he tries to run away.

John, now 17, pleaded guilty to 12 charges, with charges involving throwing a corrosive substance with intent to harm and attempted robbery. He was sentenced to 10-and-half years in prison on Monday, March 12.

The footage, shared by the National Police Air Service on Monday, was shot in July 2017, following six acid attacks in Newham, Islington, and Hackney.
