Two burglars stole cash from an elderly man after walking into his home while he was in.
The offenders went into a house in Coldwell End, Youlgrave, near Bakewell, at about 3.30pm on Tuesday, May 6.
The 87-year-old victim spotted a man in his house and was then asked to hand over cash.
A second intruder then appeared and the pair demanded that the man hand over money, before searching the house and leaving with a quantity of cash.
One of the men was white, 5ft 10ins, aged between 18 and 30 and of medium build. He wore light grey jogging bottoms and a grey top, and had a scarf covering part of his face.
The second was white, 5ft 8ins, aged about 18 and of medium build. He wore dark clothing, gloves and also had a scarf covering his face.
Police want to hear from anyone who saw the two men or might have information about the offence.
Witnesses or anyone with information should call Derbyshire police on 101 or Crimestoppers, anonymously, on 0800 555 111.
