A man has been charged after police allegedly uncovered a million-dollar hydroponic cannabis cultivation inside an industrial unit at Wetherill Park on Friday.
Green Valley police conducted investigations into the illegal cultivation and supply of cannabis in the area between August 2013 and March 2014.
As a result of investigations, four people were previously arrested and charged with a range of drug offences relating to an alleged cannabis-cultivation syndicate.
About 8.40am on Friday, March 14, Green Valley police attended an industrial unit on Blackstone Street, Wetherill Park.
They conducted a search warrant at the premises and allegedly located 340 cannabis plants, with an estimated potential street value of $1 million, being grown in a sophisticated hydroponic set-up.
Police seized the plants as well as equipment used in the cultivation of cannabis, including heat lamps, watering systems, filters and electrical transformers.
During the search, police also seized cash, loose cannabis head and a smoke grenade.
A 61-year-old man, who police will allege was the leader of the syndicate, was arrested at the premises and taken to Green Valley police station.
The man was charged with the large commercial cultivation of a prohibited plant, supplying prohibited drugs, using electricity without authority and dealing with the proceeds of crime.
Investigations into the alleged syndicate are continuing.
