Casey Crime Investigation Unit detectives are investigating a commercial burglary at a Cranbourne West construction site earlier this month.
Unknown offenders attended the address in Industrial Circuit about 7.40pm on 8 November.
The unknown offenders arrived at the site in a silver Nissan Navara towing a large trailer and a white Holden Commodore utility.
A scissor lift, valued at $25,000, was stolen during the burglary.
Investigators have released images of the two vehicles involved in the hope someone may recognise them.
Anyone who witnessed the incident or with information about the vehicles is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
