A man pushed and threatened newsagents' staff saying he had a gun in a robbery.

Police are seeking witnesses after the robbery this morning.

At 8.05am a man entered Martins newsagents in Tilgate Parade, Crawley, threatened and pushed the member of staff and took a quantity of cash, believed to be less than £100, from the safe before making off on foot.

The man said he had a gun, but one was not seen.

He is described as white, about 5'10" and of medium build. He was wearing a black hoody up, with white stripes down the arms and a Nike emblem on the front, a pale pink scarf covering his mouth and nose, long grey jogging bottoms and dark coloured trainers with a white sole.

The member of staff was shaken but not physically injured.

A police helicopter was called in to help officers search the area but the man was not found.

Detective Sergeant Mark Miller said: "If you were in the area around Tilgate Parade and saw anything that might help our investigation, please contact us online or by calling 101, quoting serial 375 of 21/07.
