A 19-year-old Brighton shop assistant has been robbed for the second time in a month.

In the latest attack she was forced to lie face-down by a knife-wielding robber who threatened: "I'm going to get you if you move."

He then rifled the till and fled with £120 and packets of cigarettes.

The terrified assistant, who was robbed at the same off-licence a month ago, was traumatised and today friends said she was considering quitting her job.

The raider burst into Mulberry Wines, in Bristol Road, Brighton, just before 8pm on Sunday.

Two men entered the shop as the robber fled and police are trying to trace them or any other witnesses.

Detective Constable Stuart Parson, of Brighton CID, said: "The victim was badly shaken by the ordeal and we urgently need to trace this man."

The robber - aged about 30, and wearing a black woollen hat and light-coloured clothing - ran into Bedford Street and from there to the seafront.
