Melton Crime Investigation Unit detectives are appealing for public assistance following a ram raid in Ravenhall yesterday morning.
It is understood three men drove three separate cars to a business in Barretta Road just before 5am on Thursday, 9 November.
Police were told one of the cars, a stolen Nissan Navara, drove through a steel gate and repeatedly rammed a roller door to gain access to the building.
Two of the men loaded three car engines into the back of a white Volkswagen Jetta and another unknown black vehicle.
The combined estimated value of the three engines is $160K.
The men fled the scene in the two loaded up vehicles and left the Navara behind at the scene.
Investigators have released CCTV footage of the men they believe may be able to assist with their enquiries.
The men were last seen wearing black clothing and one of the men was wearing a black 'Squid Games' mask.
Anyone with information or CCTV footage is urged to contact Crime Stoppers on 1800 333 000 or make a report online at www.crimestoppersvic.com.au.
