This is the moment a gang on four mopeds surrounded a tourist during a terrifying attempted robbery in an affluent part of central London.
CCTV footage released by the Met Police shows the man walking along Park Lane in Westminster, when he is suddenly besieged by the mopeds, each of which have two people on.
The vehicles even mount the pavement as they attempt to box the victim in but he is able to run away.
However one catches up with the man moments later and smashes into him on the pavement, sending both him and the moped sprawling.
Despite suffering a broken leg, the man is still able to crawl away from his attackers, who ride off empty-handed.
The incident happened shortly after 3pm on Sunday, April 30, as the man walked north on the opposite side of the road to Hyde Park.
Police said the victim - a man aged in his 30s - does not wish to be identified. He is not a UK national and he was on holiday in London at the time of the incident.
Detectives Constable Richard Kidd said: "This happened just after 3am, when a group of four or possibly more mopeds riding together would have been conspicuous.
"I want to hear from anyone who recalls seeing such a group, or who may have seen the mopeds being abandoned - or perhaps being stored in a lockup or similar location - in the early hours of Sunday, 30 April.
“One of the mopeds would have sustained damage to its left side."
Anyone with information that may assist police should call Westminster CID via 101. To remain anonymous call Crimestoppers on 0800 555 111.
