Police spokesman Michael Kwan says officers found 137 grams of marijuana and 30 grams of cocaine worth 71,000 Hong Kong dollars (US$9,200) in the operation on Lamma Island early Saturday.

Kwan said Sunday that a 25-year-old British man was charged with selling illegal drugs and that a 42-year-old British man was charged with possessing drugs. He said they were being detained, while the remaining suspects were released on bail.

Dealing dangerous drugs in Hong Kong carries a maximum penalty of 15 years in prison, while possession carries a penalty of up to seven years.
