Geelong Crime Investigation Unit detectives are appealing for public assistance to identify three people after a man was seriously assaulted in Geelong last month.
Police have been told a man was standing in a car park on Little Ryrie Street speaking with three occupants of a grey BMW sedan just before 3am on Friday December 16.
It is believed the man spoke to the unknown female driver when two unknown men got out of the car.
One of the offenders punched the victim to the face causing him to fall to the ground unconscious.
The offenders then fled the scene.
A 48-year-old Geelong man was taken to hospital with serious facial injuries.
The male offender is perceived to be Caucasian in appearance, medium build, wearing a blue cap, black earrings, black Harley Davidson jumper, grey pants and white runners.
The female is described as Caucasian, aged in her 20s with long dark hair, wearing a cream puffer jacket, black pants and black Vans shoes.
The second male is described as Caucasian with a mullet style haircut, arm, hand and facial tattoos, wearing a hooded jumper and work boots.
Investigators have released CCTV and images of three people that may be able to assist with their enquiries.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at crimestoppersvic.com.au
