A man's hands were bound with tie wraps by a gang of robbers who attacked him and raided his Doncaster home.
The three men struck at a house in Station Road, Dunscroft, at 11.30pm on Sunday, November 4.
They used tie wraps to bind their 61-year-old victim’s hands together before attacking him then raiding his home.
They escaped with cash, jewellery and cigarettes.
Detective Constable Caroline Thomas said: “The offenders then ransacked the man’s property, stealing cash, jewellery and cigarettes.
“At this time, we don’t have a description of those involved as the victim has understandably been left incredibly traumatised by what happened.
“This was an incredibly violent assault which left the victim with sustained, extensive bruising to his face and body.
“I’d like to ask anyone who saw or heard anything suspicious in the area that evening to contact us.”
