Police are looking for two men believed to have robbed a grocery store in Langley Mill last night.
Staff at the Alldays shop on Station Road were threatened with a knife before the two men took money from the till at around 9.30pm.
The man who went behind the counter is described as wearing a white hooded top with blue sleeves and black tracksuit bottoms, as well as a black scarf covering the lower part of his face.
He was of large build and white, witnesses said, and looked to be in his late teens or early 20s.
The man brandishing the knife was wearing all black, including a black scarf over the lower part of his face, and was possibly mixed race. Witnesses said he could have been in his late 20s or early 30s.
If you saw men matching these descriptions last night, call police on the non-emergency number 101.
