Police are hunting three men who forced their way into a house and demanded valuables from the occupants.
The trio struck at Fair View Road, Dronfield, at around 8.30pm on Sunday, March 15.
A Derbyshire Police spokesman said: “The men kicked open the front door at a house in. They then threatened a man and told him to hand over items, but fled empty-handed a short time later.”
One of the men was black, around 25 years old , 5ft 11 ins tall, of a medium build and spoke with a Sheffield accent.
The two other men were of a similar height and build but were in their early 20s and Asian, with thin moustaches.
Witnesses or anyone with information should call Derbyshire Police on 101.
