This is the moment a group of Good Samaritans rushed to the aid of female biker who was attacked by thugs on mopeds who were trying to snatch her motorbike.
Dramatic footage shows the victim, wearing red and white biker leathers, attempting to wrestle a thug off her bike in Sutton, south London as he tried to make off with it.
The would-be thief lashes out at the owner, punching the woman, aged in her 40s, in the face.
A man and woman rush to the rider’s aid and pull the bike to the ground, shoving the attacker away during the clip, filmed by a witness from a nearby window.
A hooded accomplice steps in to protect the thief and pushes the woman.
The yob then flees empty-handed from the scene on the back of another gang member’s moped.
