A Narre Warren South man is in custody after police intercepted an unregistered truck containing over 100 kilograms of cocaine near Wallan.
The truck was pulled over heading north on the Hume Freeway shortly after 8am, 24 August after police identified that the NSW registration had expired.
A search of the truck was then conducted and police located a quantity of frozen chickens as well as a dozen boxes of a white powder substance.
While the substance is still in the process of being forensically tested, it is believed to be approximately 120kg of cocaine.
The drugs, chicken and vehicle have all subsequently been seized.
The driver of the truck, a 23-year-old Narre Warren South man, is currently in custody.
The investigation, which will be conducted by Crime Command, remains ongoing.
