Two Taiwanese men returning from a gambling trip to Macau have been detained for questioning after attempting to enter the country with US$400,000, Taipei Times reports.
Custom officials from Taoyuan Airport discovered the cash in their luggage on a Saturday flight from Macau to Taiwan.
The suspects, which include 26-year-old Chiang and 23-year-old Chen during questioning said they had gone to casinos during their trip to Macau, where they met a man who asked them to carry some of his winnings back to Taiwan.
The pair refused to identify the man in question, or what they had been offered to carry the money.
An investigation into the source of the money has since been launched, with officials on Saturday saying they were trying to determine whether the cash was part of a money laundering scheme linked to criminal activities.
