BENICIA (BCN) — The Solano County Sheriff’s Office and the FBI seized more than 4,000 marijuana plants worth $14.5 million dollars from a Benicia warehouse Thursday, a sheriff’s deputy said.

The seizure of the 4,859 plants and three pounds of processed pot followed an investigation that began in January when 825 marijuana plants and processed pot valued at more than $2.5 million was found in a warehouse in the 4600 block of E. Second St. in Benicia, Deputy Daryl Snedeker said.

The 11 a.m. search Thursday of a warehouse in the 500 block of Stone Road in Benicia revealed a large and sophisticated growing and processing operation, Snedeker said. The warehouse was divided into 10 rooms, each with plants in various stages of growth, Snedeker said.

One of the rooms was exclusively for drying the mature plants for distribution, and other rooms were intended to increase the capacity of the operation, Snedeker said.

The warehouse contained electrical panels and large ventilation and watering systems, Snedeker said.

Deputies arrested 34-year-old Thuy Dinh, of Hayward, when he tried to flee from a back door of the Stone Road warehouse, Snedeker said. Dinh was booked in the Solano County Jail on suspicion of cultivation of marijuana, possession of marijuana for sale, conspiracy to cultivate and distribute marijuana and resisting arrest, He is scheduled to be arraigned Monday afternoon in Solano County Superior Court.

The investigation is continuing, Snedeker said.
