Investigators said on July 7 that the operation followed months of surveillance, during which officers searched multiple locations and questioned around 150 people linked to the networks.
Police identified Huynh Le Thanh Long as the alleged ringleader. Authorities said he and his associates obtained master betting accounts from unidentified operators based in Cambodia before dividing them into agent and player accounts.
The accounts were distributed to gamblers in Ho Chi Minh City and other provinces, allowing users to place bets through the Bong88 website.
Electronic data recovered by investigators showed that the two syndicates processed more than VND 3.5 trillion (approximately USD 134 million) in transactions between October 2025 and their dismantling. Police said the operation had expanded across multiple provinces through a tightly managed hierarchical network.
Authorities have charged and detained 85 suspects, including 21 accused of organising illegal gambling and 64 accused of participating in illegal gambling. Investigators said evidence against other suspects is still being reviewed.
