Police are appealing for public assistance following two suspicious fires at a Dandenong yard in Victoria over the past few months.
It is believed the first fire occurred at the business on Kirkham Road in Dandenong South on February 17 at about 1.30am.
Police allege the offenders were seen driving a black Audi sedan up to the entrance of the business, before forcing the gate open and entering the car yard on foot.
It is believed that while inside the car yard they have ignited a fire in a cabin of a semi-trailer, causing two trucks parked nearby to catch fire and destroying one of the trucks.
The second fire occurred on March 3 about 1.20am at the same premises.
The alleged offenders were seen parking a black Ford sedan in the driveway of the business before exiting the sedan and approaching a locked gate.
They gained access to the yard by cutting the lock to the gate and used an accelerant to set a Scania prime mover alight.
This caused two other trucks nearby to catch fire.
The alleged offenders have then fled the premises in the black Ford sedan.
As a result of the incident, it is estimated that the offenders caused approximately $1,000,000 in damage.
Investigators have released footage below of the two vehicles used by the alleged arsonists in the hope someone with information will come forward.
Anyone who witnessed the incident or has information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
