HUNTER Valley Police District is investigating a theft from the Aberdeen Waste Facility at the weekend.
It is believed a portable Honda generator and an air-conditioning system, including copper piping, were stolen from the premises.
"If anyone has information about these items or the crime, which would have required heavy duty bolt cutters to break the locks and doors, please report it to Hunter Valley Police District on 6542 6999 or Crime Stoppers on 1300 333 000 directly - not via Facebook," an Upper Hunter Shire Council spokesperson said.
"Unfortunately, ratepayers ultimately bear the costs of replacement and repairs, which is estimated at more than $5000.
"So if you saw something, say something."
