A Chinese national Mingchen Sun, 30, who was previously arrested following the discovery of weapons and explosives linked to a Pattaya-area case, has now been connected to more than 4,000 technology crime cases in Thailand. Authorities have seized and frozen assets worth more than 583 million baht as part of an expanding investigation into a major transnational scam network. Get today's headlines by email The announcement was made on 12 June at the Technology Crime Suppression Division headquarters in Muang Thong Thani. Police said Mingchen Sun is connected to a major scammer network associated with Prince Group and is believed to be a senior beneficiary within the organisation. The investigation stems from a vehicle rollover crash in Na Jomtien, Chon Buri, in May. Following the accident, officers searched a property linked to Mingchen Sun and discovered a cache of weapons and high-powered explosives, resulting in criminal proceedings that drew national attention. Pol Lt Gen Surapol Prembutr, Commissioner of the Technology Crime Suppression Division, said cyber investigators traced financial transactions linked to five major hybrid scam cases involving fraudulent investment platforms. The cases were handled by Din Daeng, Tao Poon and Sala Daeng police stations, together with the Technology Crime Suppression Division 2.

More than 100 million baht was allegedly routed through these accounts. Further analysis of Thailand’s online crime reporting system revealed that the accounts were linked to more than 4,000 inbound and outbound cybercrime cases. Police estimate the combined financial losses connected to those cases exceed 815 million baht. On 9 June, officers launched Operation Dragon’s Lair, conducting raids at 14 locations across Bangkok, Samut Prakan and Chiang Mai. The sites were allegedly connected to the holding of assets and movement of funds within the network. Matichon reported that authorities seized or froze assets, including luxury homes, villas, condominiums, high-end vehicles, land title deeds and digital evidence. The total value of the assets recovered was reported at more than 583 million baht. Pol Lt Gen Surapol said Mingchen Sun is regarded as a deputy-level leader or upper-tier beneficiary within the criminal organisation. Investigators believe he played a significant role in managing proceeds generated by the network’s operations. The Royal Thai Police and cyber police have established a joint task force to review all connected cases and analyse the digital evidence obtained during the investigation. Authorities say further asset seizures and additional arrest warrants targeting senior members of the network are expected as the inquiry continues.
