Sainsbury's customers were left terrifed when travellers chased them in a supermarket car park.
In the footage, filmed in Colindale, north London, two men appear in front of a car with one leaning onto the bonnet in an aggressive manner.
A woman screams for help and urges her companion to leave the car park quickly, shouting: "Get out of here, get out of here, please, please, please!"
The shoppers attempt to reverse away, but are chased by three men - one of whom tries to repeatedly cover his face.
A large section of the car park appears to have been taken over by the travellers and several caravans and other vehicles can be seen, while dogs and chickens roam the area around customers' cars.
The Mail Online were told: "We were both very afraid."
