Last week in Singapore, a husband and wife team accused of running an illegal gambling operation learned their fate. The couple, who were tagged for “unexplained wealth … disproportionate to their known sources of income,” will have to pay over SGD$1.3 million (US$826,000) in restitution for leading a non-licensed betting service that involved the 4-D lottery.

According to a report by The Strait Times, following an investigation led by the Commercial Affairs Department (CAD) and the Criminal Investigation Department (CID), it was determined that 60-year-old Heng Ee Howe had been involved in the illegal activity for as long as 15 years along with his wife, 55-year-old Tin Suh Chyong. The alleged activity had run from June 1, 2010 to June 3, 2015.

Heng had been collecting illegal 4-D bets on behalf of other individuals. He would then consolidate the bets and send them to gambling runners in Malaysia. He received commissions based on a percentage of the total amount of bets that were collected, as well the winnings of the gamblers.

Last year, Heng was sent to prison for three months and ordered to pay a fine of $360,000. His wife spent two weeks behind bars and had to pay $100,000 in fines. The couple’s bank accounts were frozen and an embargo placed on the condominium they owned in order to prevent any assets from being liquidated.
