Customs officers on Wednesday said three people charged over a drugs case earlier this year are now also suspected of laundering money to the tune of HK$53 million.

A fourth suspect was arrested in Sai Wan Ho on Tuesday over the alleged money laundering. The man, 41, was later released on bail.

Two women and a man, aged 23 to 25, continue to be remanded in custody in connection with the HK$28 million dangerous drugs case, officers said, adding that their investigation into the suspected money laundering is still ongoing.
