An axe-wielding robber has been wrestled to the ground by a have-a-go hero after a gang of would be thieves tried to smash their way into a jewellery shop.
The gang turned up on motorbikes at a jewellers on Victoria Street just before 1pm armed with hammers and axes.
As they tried to get away, a member of the public grabbed one of them, bundled him to the ground and kept him there until police arrived. The rest of the raiders rode off towards Belgrave Square.
Scotland Yard says it believes the robbers had fled empty-handed.
