Police Scotland has released images of two men they wish to trace in connection with their enquiries into a serious assault in Edinburgh’s city centre last year.

A 29-year-old male suffered a fractured shoulder and was treated in hospital following the attack, which happened on George Street at around 3.30am on Sunday 4 November 2012.

Detectives are keen to trace the males pictured within the CCTV footage who were seen to be in the area at the time of the assault.

Anyone who recognises the images is asked to contact police immediately.

Detective Constable Carole Sneddon said: ” The victim suffered a painful facial injury as well as a fractured shoulder which required surgery.

“The males pictured are believed to be of significance to our investigation and anyone who can assist in tracing them is asked to come forward.

“Similarly we would ask these males to get in touch with police themselves and help with our investigation.”

Those with information can contact Police Scotland on 101 or the charity Crimestoppers in complete anonymity on 0800 555 111.
