This is the shocking moment a phone snatcher is captured being knocked off his bike by furious Londoners before losing a shoe that police later used to catch him.

Spencer Duarte, of Saffron Walden, was tackled off his e-bike by members of the public after he stole a phone from an innocent victim's hand in Ludgate Hill, London, on August 7 last year.

Dramatic video footage showed the moment a quick-thinking pedestrian leapt into the street and intercepted the robber, who fell into the road while on his bike.

Duarte, who initially stood up and was able to get back on his bike, was then chased down by two more members of the public. Cornered on the side of the pavement, he was pulled from his bike a second time as he attempted to flee.

The phone thief, dressed in a flourescent top and helmet, then proceeded to run across the road away from the furious Londoners.
