Ten individuals were arrested after an online gambling ring was taken down by Vietnamese police.

Authorities say the huge gambling ring, which had been operating since July, operated throughout several provinces in Vietnam. Multiple user accounts were created on an American based gambling portal Bong88, which served hundreds of Vietnamese gamblers and raked in more than VND600 billion (US$25.7 million) in bets, VN Express reported.

According to Quang Nam Province Police, the ring was formed by Huang Quoc Viet, 37, who, along with accomplices resorted to extortion to collect payments. In addition, firearms and VND400 million in cash were confiscated in the police operation.

The police added that three of the ten suspects had surrendered themselves. In Vietnam, gambling is illegal and can lead to prison sentences for those convicted of taking part in gambling activities.

In March this year, Vietnamese authorities arrested a cyber crime police chief who was allegedly involved in one of the largest gambling ring busts in Vietnamese history, which led to 83 people being arrested. The gambling ring was said to have been valued at US$422 million.
