Police have released CCTV and are appealing to the public to help identify a man following the theft of construction machinery in Sunshine West last month.

He then loaded three Caterpillar 239D skid steer loaders onto a stolen truck.
The truck, a Hino Tautliner, was recovered in Kew on 19 May, but the loaders remain missing.
The three loaders have a combined retail value of $240,000
Investigators have released CCTV footage of a man who they believe can assist with their enquiries.
