A woman chases the man who snatched her purse in a Barking shop in this footage that's just been released by police.
The robbery happened in the Londis on Station Parade in Barking, just before 10.30am on Saturday 21st May.
As the footage shows, the suspect has only set foot in the shop when he spots the woman's purse. He heads straight for her, grabs the purse and sprints out of the shop.
The woman gave chase but couldn't prevent the thief escaping on bike towards Cambridge Road.
The suspect is described as a white man in his mid 20s wearing a grey hooded top, grey tracksuit bottoms, and black and white trainers.
