Soccer is the most popular sport and gambling is rampant, despite being strictly illegal.

In April, local side Vissai Ninh Binh withdrew from the V.League over a match-fixing scandal in the Asian Football Confederation (AFC) Cup.

Police made dozens of arrests during the World Cup and carried out raids on underground gangs that were handling at least 6.5 trillion dong ($307 million).

Local soccer bosses have pushed to legalise sports betting in conservative Vietnam to stifle match-fixing and boost tax revenues, capping bets at 1 million dong (nearly $50), but after 14 years, efforts have proved fruitless.

The six Dong Nai players were questioned by police investigators immediately after their 5-3 defeat by Quang Ninh in a top flight V.League match, Vietnam Television said in an online report (vtv.vn).

HANOI, July 21 Police have detained six Vietnamese soccer players on suspicion of throwing a domestic league game at the weekend, state-run media reported on Monday, the latest arrests in a country notorious for match-rigging and illicit sports gambling.

Police declined to comment.
