Three men have been arrested at a Springvale unit over an alleged cannabis trafficking ring across the South East. Caulfield Divisional Response Unit detectives raided an allegedly booby-trapped factory housing a ‘$2 million street-value’ cannabis crop on Mill Street, Cheltenham as well as the unit on Windsor Avenue Springvale about 7am on Wednesday 24 September. Police say they dismantled a sophisticated set-up in the factory, seizing more than 500 cannabis plants weighing about 400 kilograms. Boobytraps were placed inside the factory, including live wires, which can be deadly when stood on, with one officer narrowly avoiding injury, police allege. They were charged with trafficking a large commercial quantity of cannabis, cultivating cannabis and possessing proceeds of crime.
