A Spreckels Park business park that includes a dance studio and an engineering firm yielded an $8.4 million pot bust.

The warehouse marijuana plantation uncovered Wednesday by Manteca Police officers led by Sgt. Chris Mraz led to connections in South San Francisco where officers served a second search warrant.

Police were tipped off through an anonymous source. The marijuana could be smelled outside the warehouse loading dock even after police had confiscated the 584 mature plants weighing 2,029 pounds.

Detectives met and later arrested Lan Dinh Vuu, 34, of Stockton, as he approached the door of the commercial warehouse at 1320 Dupont Court.  They presented him with a search warrant for his leased location in the industrial area east of Spreckels Avenue facing the transition ramp to the 120 Bypass.

Officers found that the warehouse area had been divided into three separate marijuana grows with mature plants ready to be harvested in each of the rooms with a street value of $8.4 million. They had extra large buds – making them more valuable. The rooms were outfitted with exhaust fans and commercial grow lights.

Police said the grow demanded an excessive amount of electricity to serve the needs of the plants since last July.

The indoor marijuana nursery was expected to be harvesting the plants next week intended for a South San Francisco marijuana store.  Detectives had continued their investigation in the Bay Area residence and linked a suspect to Vuu. 

During a search of that residence they located $130,000 which was linked to proceeds from the marijuana cultivation and sales and also recovering a weapon which they confiscated.

Vuu was transported to the San Joaquin County Jail and booked on felony charges of marijuana cultivation, possession for sale and conspiracy. He is being held in lieu of $120,000 bail with a court date set for Nov. 16 at 1:30 p.m. in the Manteca Branch of the San Joaquin County Superior Court.
