Police are appealing for information following a robbery in Bradford.
At about 7.45pm on Tuesday, 6 January, a man forced his way into a house in Duckworth Lane and demanded jewellery from the 83-year-old male occupant.
Following an altercation, the elderly man was ordered to lie down and keep quiet while the house was searched.
It is not known if anything was stolen.
The victim suffered a cut to his forehead which required hospital treatment.
The suspect who forced his way into the property is described as white, about 6ft tall and of athletic build.
He was believed to be between 30 and 35 years of age and was wearing a dark hat and a dark top.
Detective Inspector Neil Benstead, of Bradford District CID, said “This must have been a terrifying ordeal for the elderly victim, who was alone in the house at the time.
“It is believed that the man who forced his way into the property was accompanied by another suspect, so we would appeal to anyone who may have seen two males acting suspiciously in the Duckworth Lane area in the time leading up to, or shortly after the incident.”
Anyone with any information is asked to contact DC 251 Gill at Bradford District CID on 101 or Crimestoppers anonymously on 0800 555111.
