A ROBBER threatened to stab a Tesco employee in the foot after a man tried to steal two boxed DVD players from the supermarket.

The worker was trying to escort one of the robbers out of the store in County Way, Trowbridge, at about 9.15pm on Wednesday.

The man called out to another man outside the store, telling him to stab the worker.

The employee released the offender, fearing he was going to be assaulted.

Police believe the two men and a woman left in a white Renault 21, which had been parked in the store's car park. They drove off towards the Longfield roundabout.

Officers are trying to trace a woman who gave the store the car's registration details.
