A robber threatened workers at a West Sussex off-licence with a knife and stole cash and cigarettes, police revealed today.

Thresher in Station Parade, East Preston, fell victim to the latest in a spate of off-licence hold-ups on March 9 at about 8.55pm.

The robber was 5ft 8in to 5ft 9in tall, slim and wore dark clothing.

Detective Constable Keith Fifield said: "We are appealing to the public to come forward if they saw anything suspicious before or after the robbery.

"We are linking this robbery to the Thresher robbery on March 3 at The Street, Rustington. But at this stage it is not believed to be connected with any other off-licence robberies."

Last week, police released a CD-fit image of two of three men who grabbed a female worker while holding up Thresher in High Street, Billingshurst, on February 17.
