Hume Crime Investigation Unit detectives are seeking public assistance to help identify three males following a burglary in Tullamarine last month.
It is believed three males attended the South Centre Road business just after 11pm on 14 December in a dark-coloured Ford ute.
One male remained in the vehicle while a second male attempted to pull the factory doors off with a snatch strap.
The driver reversed into the door multiple times, smashing it open and allowing entry to the factory.
Two males then loaded the vehicle tray with a large amount of electrical diagnostic equipment before driving off.
Investigators have released images and CCTV of the males they believe 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 www.crimestoppersvic.com.au
