Customs & Excise officers seized 6kg of methamphetamine and a small amount of crack cocaine, worth over $4.9 million, and arrested two men and a woman at the airport.

The trio had joined a tour group to New Zealand. Officers stopped them yesterday and found the methamphetamine in two of their suitcases.

On a later search of the other man's flat in Tsuen Wan, they found 123g of crack cocaine and some drug packaging equipment.

The three, aged 37 to 39, were charged with trafficking in a dangerous drug. They will appear at Tsuen Wan Magistracy tomorrow.
