Hong Kong police arrested four men on Sunday, seizing HK$10 million worth of cannabis. Officers from the Narcotics Bureau ambushed a 48-year-old suspect at a car park at Chui Tin Street in Sha Tin at about noon. Inside his car, 136 packs of cannabis in nine boxes – weighing 35kg in total – were found. Police also approached two suspects in another car park on the same street as they were boarding a seven-seater. The men tried to flee in the car and collided with a police vehicle. The driver, 21, and his passenger were, 38, subdued and arrested. A total of 80 packs of cannabis weighing 23kg were found in the car. No one was injured. Four arrested and HK$19 million worth of cannabis seized during Hong Kong police raids At about 3pm, police raided a 19 square metre flat in an industrial building on Sui Wo Road in Fo Tan and arrested a 20-year-old man. The site is suspected to have been used as a storage area for the contraband. The 58kg of cannabis seized during the first two arrests had a total estimated market value of HK$10 million. Police believed the haul was imported from abroad and was intended for sale to local users. The four men arrested, all Hong Kong residents, have been detained. Police said the operation would be continued and further arrests were possible.
