Police investigating an assault where the victim suffered a fractured jaw have released CCTV stills of men they want to speak to.
A 46-year-old man was in the Aruba bar in Corporation Street, Chesterfield, in the early hours of Sunday, September 13, when the incident took place.
He was struck to the head and knocked to the floor by an attacker he did not see.
He later attended hospital where scans revealed the injury to his jaw.
A Derbyshire police spokesman said: “Officers are now appealing for help identifying a group of men they want to speak to in connection with the incident.
“Do you recognise any of the men in the CCTV images? Do you recognise their clothing?”
Anyone with information should call Derbyshire police on 101, quoting crime reference 39623/15, or Crimestopers on 0800 555 111.
