The man, who was admitted to hospital after the assault, was followed from Colomberie by the assailant in the early hours of Saturday morning and confronted on Mont Millais, outside the old Post Office site.
The attacker, thought to be a man aged between 20 and 25 years old, rained kicks and punches on the victim in a sustained attack that lasted for over ten minutes.
The man was later treated for numerous cuts and bruises to his face, head and hands and has now been released from hospital.
