Police have appealed once again for any withnesses who may have been in the Bath Street area around 3.30am on Saturday, September 26.
The re-appeal comes as detectives search for two men who may be able to help them with their investigation into the assault of two men.
The first of those police want to speak to is described as white, aged 20 to 25, between 5ft 10in to 6ft in height with slim build and short hair.
He was wearing a long-sleeved polo top and dark jeans.
A second man is described as white, aged 20 to 25 years, between 6ft and 6ft 2in in height and of slim build with dark-coloured hair. He was wearing a dark-coloured polo top.
Detective constable Blair Duncan, of Greater Glasgow Division CID, is appealing for any witnesses to this incident, or anyone who can identify the men in the images, to contact Police Scotland on 101.
Alternatively, Crimestoppers can be contacted on 0800 555 111, and anonymity can be maintained.
