The man stepped outside of a nearby hotel sometime between 2-4am on Sunday, April 7 and, it is thought, was attacked, suffering serious head and facial injuries as a result. The man is in a stable condition in hospital at present.
Police understand that a number of late night passers by tended to the man following the assault, and ask that those people come forward.
It is possible that others may have witnessed the assault, and again police would like to hear from any witnesses and anyone who may saw suspicious activity in the area at that time.
Police can be contacted on 0845 600 8000 or Crimestoppers on 0800 555 111.
