Brimbank Sexual Offence and Child Abuse Investigation Team detectives are investigating an alleged sexual assault that occurred in Eynesbury in 2021.
A 12-year-old girl met up with an unknown man she had met online in the carpark of a general store on Eynesbury Road at about 10.30pm in December.
The pair walked to an abandoned building in the historical park, about 20 minutes away from the store.
It is understood the man sexually assaulted the child, before returning to the carpark.
A complaint regarding the incident was reported to police in May this year and an investigation commenced.
Police believe the man was driving a utility, described as having a white cab, an alloy tray and a ladder on top.
Police have released a computer-generated image of a man they believe may be able to assist them with their inquiries.
He is described as being in his mid to late-30’s with dark orange hair, stubble, and being of medium build.
He was wearing a dark pink/burgundy t-shirt and told the victim he resided in the Tarneit area.
Anyone who recognises the man or with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au.
