Vietnam continues to punish those involved with a major online gambling ring the authorities disrupted this spring.

In March, Vietnamese authorities announced that they’d taken down an illegal online gambling ring based in the province of Phú Thọ that involved the cooperation – both active and passive – of some of the nation’s top cops and telecom operators.

The ring centered on an online casino game called Rikvip that required players to buy virtual credits for online play but which could be redeemed for real cash should a player wish to cash out. Police said the game attracted millions of users who spent VND9.8t (US$426m) in the nearly three years the ring was in operation.

On Wednesday, Vietnam News reported that the Phú Thọ People’s Procuracy had confiscated VND372b ($15.9m) from three mobile operators – Viettel, Vinaphone and Mobiphone – through whose mobile top-up cards the game play was funded. The People’s Procuracy has required online payment processors and 33 banks to similarly cough up their ill-gotten proceeds.
