Video: Shocking footage of the moment fearless have-a-go hero tackled an armed robber

Brave Darren Baker got Stephen Lawrence, 54, in a headlock before forcing him to the ground when he tried to rob a shop in Norwich on December 22 last year.

Mr Baker raced to the Premier Stores shop after his wife Sharon, 42, told him there was a man inside wearing a crash helmet with a sawn-off shotgun. Despite having the imitation firearm pointed directly at him Mr Baker grabbed the motorcycle helmet Lawrence was wearing and forced the crook to the floor. In the meantime a shop assistant who had fled the store called police who came and arrested Lawrence.
