Vietnamese authorities are celebrating the dismantling of a massive illegal online sports betting ring linked to the Fun88 brand.

On Thursday, the Thanh Nien news outlet reported that Vietnam’s Ministry of Public Security had arrested 22 individuals suspected of involvement in an illegal online gambling ring that authorities are describing as one of the biggest ever rumbled in the country.

Two days earlier, police staged simultaneous raids in several cities, including Hanoi and Ho Chi Minh City, seizing “hundreds” of electronic devices and other tools of the gambling trade, along with numerous luxury vehicles and “large amounts of cash and bank accounts with large account balances.”

The Agence France Presse wire service reported that the gambling operation handled wagers totaling US$1.28b, although the time frame in which this sum was processed went unspecified. The authorities said the betting ring’s customers were asked to deposit cash into bank accounts in exchange for virtual credits that could be used for wagering purposes.
