Quinte West OPP investigating the theft of $200,000 worth of butter from a trucking facility in Trenton.
Four people broke into the Glen Miller Road compound late Christmas night after being dropped off nearby by someone driving a black SUV.
The suspects attached two trailers, each loaded with a about 20,000 kilograms of butter, to two transport trucks and drove off.
The transports and trailers were located Monday, one in Etobicoke, the other in Toronto, with their contents emptied.
Anyone with information is asked to contact Ontario Provincial Police or Crime Stoppers.
