A man was knocked unconscious after a fight outside a takeaway on Friday night.
The 48-year-old victim was punched repeatedly and kicked in the head at around 10pm in Newcastle Avenue in Worksop.
He was taken to Rotherham Hospital and treated for a broken nose, a cut lip and a swollen right eye.
It is thought the victim was attacked by four men and police are appealing for witnesses to come forward.
Inspector Hayley Crawford, of Nottinghamshire Police, said: “This was a shocking incident and it’s very fortunate that it didn’t result in more serious injuries.
“Officers are continuing with their enquiries to establish the full circumstances of this incident, including trawling through CCTV footage.
“We take incidents of disorder such as this very seriously. The use of violence is totally unacceptable and we will always look to take robust action against those who commit such offences.
“We believe there were a number of witnesses and we are asking anyone who saw what happened to contact police on 101 quoting incident number 768 of 18 June.”
