Shock footage has been released showing a South London moped gang spraying pedestrians with fire extinguishers as they drive around streets in a recorded rampage.
A bus stop, smokers outside a pub and people walking under a tunnel are all victims of the prank - which the man recording the attack apparently finds hilarious.
The footage was shot in Wimbledon and Wandsworth.
The brazen gang even shoot white foam at a police car at a petrol station.
