Fawkner Embona officers are investigating after shots were fired in Hadfield last month.
It is understood a man got into his vehicle, which was parked on the corner of West Street and Eileen Street, about 9.55pm on 26 August.
He drove towards Pascoe Vale, past a parked black sedan on Grevillia Road which had its headlights on.
Police were told the black sedan followed the victim's car before shots were fired at the vehicle at the intersection of Quick Street and Arndt Street.
The black car fled the scene.
There were no physical injuries during the incident.
Investigators have released vision of a black vehicle, in the hope that someone recognises it or knows who was inside it at the time.
Anyone who witnessed the incident, has dashcam/CCTV footage or information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
