Co-op workers in Ewell threatened with knife and hammer

Armed robbers have made off with "a sum" of cash after threatening two supermarket workers with what is believed to be a knife and a hammer.

Two men entered the Co-operative store in Ewell High Street, Surrey at about 22:40 GMT on Tuesday, police said.

They threatened the staff before making off with the money.

There were no customers in the store and no-one was hurt, Surrey police said. Officers are appealing for witnesses.

The suspects are described as white, in their late 20s or early 30s, and of slim build.

They were wearing black trousers, hooded tops, dark gloves and face masks, the force spokesman added.
