E-bike thieves brazenly ripped a phone from a man's hand on a busy street corner in one of London's poshest neighbourhoods.
The stunned pedestrian chased after them in Knightsbridge, west London but was forced to give up when the thieves zoomed off.
The two riders targeted the man who was carrying a white bag and casually standing by the kerb with a woman.
It appeared as if he was about to cross the road when the main culprit, clad in black, snatched the phone from his hand.
The phone snatch was filmed on February 14.
