The raid followed complaints from local residents who reported that several migrant workers were living inside the warehouse and suspected illegal activity was taking place. Investigators from Metropolitan Police Bureau Division 9 and the Food and Drug Administration monitored the property in Bang Bon 4 Soi 6, Bang Bon Nuea, and observed vehicles entering and leaving while suspicious bags and boxes were transported in and out.

Police later obtained a court-approved search warrant and entered the premises. Inside, officers discovered the warehouse had been converted into a large indoor cannabis cultivation site equipped with ventilation systems and numerous air-conditioning units.

Authorities arrested seven Vietnamese suspects identified as Mr. Nguyen Doan Trinh, 31, Mr. Tran Ngoc Phong, 52, Mr. Ho Ngoc Bang, 47, Mr. Nguyen Huu Son, 45, Mr. Nguyen Dinh Sang, 32, Mr. Viet Huy Luong, 38, and Mr. Binh Duong Dang, 46.

Investigators said they found no licences relating to cannabis cultivation, processing or distribution. Officers also seized two Lanphan freeze dryers, a hydraulic rosin press, a heat press, a powder filtering machine, a cement and paint mixing machine, plastic mixing tanks, weighing equipment, hydraulic pressing equipment and several freezers.

Senior officers involved in the operation included Metropolitan Police Commissioner Lt Gen Siam Boonsom, Lt Gen Noppasin Poolsawat, Maj Gen Theeradej Thamsuthee, Maj Gen Phanlop Aremlau and Maj Gen Samart Promchart. Officers from Bang Bon Police Station and the Office of the Narcotics Control Board also took part in the raid.

Police said the suspects face charges of jointly producing a Category 5 narcotic substance, namely cannabis extract, without authorisation. Authorities also filed charges related to employing foreign workers without valid work permits.

Khaosod reported that the seven suspects were transferred to investigators at Bang Bon Police Station for further legal proceedings. Authorities are expected to continue examining the operation and any possible wider network connected to the warehouse.
