Police have released an image of two men they believe witnessed a violent assault in Leigh.
In the early hours of 31 August 2013, a 31-year-old man was on King Street in Leigh near its junction with Bradshawgate.
He was approached by the offender and punched in the face. The force of the blow knocked him unconscious. He was treated in hospital for facial injuries.
The offender is described as white, 6ft tall, with brown hair, short on top and longer at the back and he was wearing a grey top and blue jeans.
Detectives have released a CCTV image of two men believed to have been out with the offender that night and are appealing for the public’s help to identify them.
Detective Constable Kevin Byrne said: “At this stage it appears this was an unprovoked assault that caused the victim some nasty injuries.
“We have made numerous enquiries to try and identify the offender but at this time he remains unknown.
“We have reviewed many hours of CCTV and are now trying to identify the two men in the image that we have released as we believe they were out with person responsible and can help us identify him.
“If you recognise yourself in this image or you know who either person is please call us.”
