Police on Sunday said they had arrested and charged six people after seizing drugs worth HK$10 million.
The force said it took action on Thursday after receiving reports about a suspicious-looking pair who came out of a flat in Kwai Chung.
Officers said 12.5 kilogrammes of illegal drugs were found in the operation.
Five men and one woman were charged with conspiracy to manufacture and traffic in dangerous drugs.
Police said the six would appear before West Kowloon Magistrates’ Court on Monday.
