Car Crash Uncovers Massive Scam Network: Chinese Suspect Linked to 4,000+ Cases, $583M Baht Assets Frozen

;

A routine traffic accident has unexpectedly exposed a suspected cross-border criminal network involving weapons, explosives and a massive online scam operation.

On June 12, Thailand’s Cyber Crime Investigation Bureau (CCIB) held a press conference at its headquarters in Muang Thong Thani, Nonthaburi, announcing the latest developments in a major operation codenamed “Dragon Nest Blast.”

Thai authorities said they have seized and frozen assets worth more than 583 million baht (approximately RMB 120 million) during investigations into Chinese national Mingchen Sun and his alleged network.

The case came to light in May after Sun, 30, was involved in a vehicle rollover accident in the Na Chom Thian police jurisdiction of Chonburi Province. During a follow-up investigation at his residence, police discovered a large quantity of weapons and high-explosive materials, triggering a wider criminal investigation.

As investigators expanded their probe, Thai authorities suspected that Sun had links to the major scam network Prince Group and began tracing his financial activities and alleged criminal connections.

According to Lieutenant General Surapong, chief of Thailand’s Cyber Crime Investigation Bureau, investigators compared Sun’s case with five major “hybrid scam” cases handled by different police units.

The investigation found that bank accounts under Sun’s name had received large amounts of money transferred through multiple “mule accounts,” with total transactions exceeding 100 million baht.

Further analysis through Thailand’s online crime reporting database showed that the accounts were connected to a large number of technology-related crime cases. Authorities have so far linked the accounts to more than 4,000 scam cases, causing total losses exceeding 815 million baht.

To trace suspected criminal proceeds, Thai police launched a major operation on June 9, conducting searches at 14 locations across Bangkok, Samut Prakan and Chiang Mai.

During the raids, officers seized and froze a range of suspected assets, including luxury houses, villas, condominiums, high-end vehicles, land documents and electronic devices. The total value of frozen assets exceeded 583 million baht.

Police stated that, based on current evidence, Sun was not believed to be a minor participant but may have played a key role within the alleged transnational criminal network, potentially acting as a senior figure or major beneficiary.

Thailand’s national police and cybercrime authorities have established a joint task force to further analyze digital evidence, track financial flows and identify additional individuals allegedly involved.

The investigation remains ongoing, with authorities warning that more arrests and asset freezes may follow as they continue dismantling the suspected cross-border scam network.
