The Hume Police District has reminded residents to be on the look-out for people posing as tradespeople.
In December, police issued a warning about tree looper canvasing streets in the Highlands to commit break-and-enter offences.
People are wearing high-visible work shirts but have no tools, no trade vehicles, and are looking for residences that are unattended and where stealing is an opportunity.
Police have had reports of suspicious person at Colo Vale/Hill Top/Buxton areas.
If you see anything suspicious, write down the number plate details and a description of the vehicle/person and contact Southern Highlands Police immediately on 4868 1222.
