Customs arrested a man after discovering 6.3 kilograms of suspected cocaine worth about HK$6.9 million in four cookie tins.
Officers were doing a routine check on a foreign man arriving from Macau on Saturday before finding the tins suspicious and opted to open it to check the contents.
They then found 6.3 kg of suspected cocaine with a market value of HK$6.9 million.
The man was arrested on suspicion of trafficking in dangerous drugs and the case has been handed over to the Customs Drug Investigation Bureau.
The customs revealed that the 26-year-old was given a cash reward of several HK$10,000 to help carry the cookie cans to Hong Kong.
The Customs added that his route to Hong Kong was very roundabout.
Within the first 10 days, he departed from Bahrain and passed through Istanbul, Addis Ababa, Manila, and Macau before finally taking a ferry to reach Hong Kong to hand over the batch of drugs to other people.
This is the second instance of drug smuggling using cookie tins after the customs arrested a 62-year-old foreign woman who smuggled 6.5kg of suspected cocaine on Thursday (Jul 6).
