Police Scotland are appealing for information after a 20-year-old man sustained a head injury after being attacked in Edinburgh’s city centre on December 11.
Detectives say that the incident occurred around 10:10pm in Meuse Lane when the 20-year-old was understood to be in a conversation with four men.
He is understood to have sustained a head injury and was taken to the Royal Infirmary of Edinburgh by ambulance for treatment.

Two were bald, whilst one had short, dark hair and the other was wearing a dark coloured woollen hat.
