A thief is being hunted by police for brazenly strolling out with a shopping trolley filled with stolen stuff - before threatening to stab supermarket workers.

Police have released footage of the suspect who allegedly tried to steal more than £500 worth of goods from Sainsbury's in Crayford, south east London.

The clip shows a man in a hi vis jacket and shorts pushing a full trolley outside the shop on August 28.

Two staff members are seen to approach him, prompting him to run off towards the car park.

A police spokesman said: "He ran off when challenged by staff but when caught stated he had a knife and wasn't afraid to use it."
