San Gabriel Police Department served a search warrant at a commercial property located at 100 South San Gabriel Boulevard and discovered an illegal marijuana cultivation operation containing over 4,200 plants.
The illegal marijuana cultivation operation was housed inside a 42,000 square foot building at the east portion of the property that was previously used as a vehicle service area and auto body shop. This initial large scale grow consisted of several rooms containing over 4,200 marijuana plants in various stages of maturity, supported by artificial lighting as well as sophisticated hydroponic and ventilation systems.
Phong Day Ung, a 36 year old male from Rosemead, was found working inside the location and arrested at the scene for felony marijuana cultivation.
As detectives continued their search of the property, another separate marijuana grow was found hidden inside a building directly under the main office area at the northwest portion of the premises.
Although this building was void of any visible entry points from the outside, it was later found to contain several fabricated interior rooms and a similar marijuana cultivation operation containing over 2,600 plants that included a secret interior passage way to the upstairs office.
Yuntong Zheng, a 34 year old male from Monterey Park, was also arrested for felony marijuana cultivation when he returned to the scene.
San Gabriel police said in a statement that the search warrant service was the culmination of a two week long investigation by Special Enforcement Team detectives based on an anonymous tip from a citizen. The investigation is ongoing as detectives are working to determine if the two marijuana grows found at the commercial property are linked or independent operations.
In addition, San Gabriel Fire Department and Code Enforcement personnel responded to the location to assess the safety conditions and business licensing requirements for the property.
