Police are appealing again for information following an armed robbery at a Shirebrook house.
Two men walked into a house in Field Drive on January 25 and an argument broke out between them and the two men and one woman inside.
One of the burglars fired a shot into the wall and the two men stole cash before driving off in a car. No one was injured. The man with the gun is described as 5ft 7ins and stocky. He wore a black balaclava and dark clothing.
His accomplice is 5ft 10ins and wore a green military-style jacket, dark trousers and a black balaclava.
He was holding a knife.
Both men are white.
A small, light-coloured hatchback car was seen in the area.
Anyone with information, who has seen the car, who was in the area of the night of the offence, or can help the investigation in any other way, should call police on 101 or contact Crimestoppers anonymously on 0800 555 111.
