Geelong Crime Investigation Unit detectives are investigating after a man was assaulted in Geelong last year.
It is understood the victim, a 26-year-old man, was walking along Moorabool Street about 7pm on Saturday 13 December.
Officers believe an altercation between the victim and an unknown man occurred which lead to the victim hitting his head on the footpath.
The unknown man initially checked on the victim but fled towards Easten Beach when other passersby approached to assist.
The victim was taken to hospital with serious injuries.
Investigators have released an image of a man who may be able to assist with enquiries.
He is described as being Caucasian, in his mid-20's, with black short hair and has distinctive leg tattoos.
He was seen wearing a black shirt, black shorts and black and white shoes.
