On 9/6, Nguyen Van Tuan, 38, a resident of Ho Chi Minh City, along with 26 others, were arrested and temporarily detained by Nghe An Provincial Police on charges of money laundering and gambling.

According to the investigation, in 2025, Tuan established an inter-provincial gambling ring. He recruited numerous agents to attract players in Nghe An and various localities through the Sunwin website, offering forms of gambling such as sic bo, casino games, card games, and football betting.

Tuan directly managed operations, using the Telegram application to communicate and instruct subordinates. He frequently changed transaction accounts and operational methods to avoid detection. The banking account system was structured into multiple intermediary layers to conceal the money flow, which was then converted into USDT cryptocurrency.

Months ago, while monitoring cyberspace, Nghe An Provincial Police detected signs of the ring's activities and subsequently launched a special investigation.

From 25/5 to 5/6, Nghe An Provincial Police, in coordination with the Ministry of Public Security and police from multiple provinces and cities, formed 20 task forces. They simultaneously raided locations associated with the ring in Nghe An, Ho Chi Minh City, Thanh Hoa, Ha Tinh, Vinh Long, Dong Nai, Dong Thap, and Gia Lai. Police arrested 27 individuals and seized 27 mobile phones and 6 computers.

Investigators determined that from 5/2025 to 5/2026, the suspects moved and concealed over 2.8 million USD, equivalent to more than 75 billion VND, through the banking account system and cryptocurrency trading activities.

The case is currently under expanded investigation.
