Two individuals have been arrested for allegedly smuggling 4,705 grams of heroin into Taiwan, police in Kaohsiung announced Saturday.
Police said one of the suspects, surnamed Chen, purchased the heroin in Thailand and hid it in the wall of a specially made 20-kilogram iron barrel to skirt its detection by X-ray machines.Chen also tightly sealed the lid of the barrel with wax and covered it in butter to prevent sniffing dogs from picking up the illicit drug's scent.He then mailed the barrel to Taiwan by air mail to a Kaohsiung County resident surnamed Fu, declaring the shipment as motorbike parts and components.Acting on a tip, police raided Fu's residence in Kaohsiung County Friday and seized the heroin before arresting Chen in Kaohsiung City later the same day.
