A man holding a knife demanded a female cashier open the till during a burglary at an off licence on Station Road in Long Eaton.
At around 11pm on July 10 two men entered Discount Drinks as the staff were locking up and demanded cash off the staff member.
A male member of staff then chased the men off. One is described as white, aged around 30, wearing a black and white top. The other was wearing a grey T-shirt and jogging bottoms. Anyone with information should call police on 101.
