Police have released CCTV footage of an armed robbery at a jewellers in East Yorkshire.

Two men stole watches worth "tens of thousands of pounds" after forcing their way into Guest and Philips in Beverley, Humberside Police said.

They threatened staff with a sawn-off shotgun, but no shots were fired and nobody was injured.

Officers are looking for four men, two of whom were the drivers of two silver coloured getaway cars.

The two men who raided the shop were wearing white overalls and black balaclavas.
