The police spokesperson confirmed that the case involving the "Chinese man" known as Ce Four, linked to a Cambodian scammer gang, has found no evidence of involvement by Thai politicians. Authorities are conducting foreigner screening over three months and setting up a Joint Task Force connected to "One Police." They confirmed current evidence shows no indication of sabotage plans within Thailand or preparations to use weapons to harm Thai citizens.
At 11:00 a.m. on 13 May 2026 at the Royal Thai Police headquarters, Police Lieutenant General Trairong Phiwpan, spokesperson for the Royal Thai Police, provided an update on the security case involving 31-year-old Chinese national Ming Chen Sun. He had a traffic accident in Chonburi province, after which police searched his luxury residence in Pattaya and found numerous weapons, including C4 explosives, two M4 assault rifles, and hidden grenades.
The case has progressed significantly as police gathered more evidence, including witness testimony, circumstantial evidence, financial trails, forensic data, and digital information. They uncovered chat histories, images of weapons training, and weapons accumulation dating back to late last year.
"Based on all evidence, it is clearly linked that Ming Chen Sun is involved with a scammer network in Cambodia. Regarding rumors that the suspect was hired for assassinations in Cambodia, the police are still investigating all aspects before confirming the facts clearly," he said.
Regarding speculation linking the case to Thai politicians, the police spokesperson stated that so far no information indicates the suspect has any connection with Thai politicians. He reaffirmed that current evidence shows no signs that the network aims to commit sabotage in Thailand or plans to use weapons to harm Thai citizens.
Police Lieutenant General Trairong said that following the investigation, originally only Ming Chen Sun was a suspect, but five more suspects have been identified, totaling six. Additional charges are expected to be filed soon.
When asked about Ming Chen Sun’s severe stress leading to seizures and his transfer from prison to hospital treatment, raising concerns about a possible escape attempt, the police spokesperson said the suspect is under the Department of Corrections' care. The National Police Chief, Police General Kittirat Phunpet, has ordered the Provincial Police Region 2 to enforce maximum security measures, even as the suspect receives medical treatment under his basic rights.
"The Royal Thai Police also plan to review and upgrade foreigner screening procedures for those entering the country. The National Police Chief has ordered the Immigration Bureau to intensify monitoring of foreigners residing in Thailand abnormally long, and to coordinate with local police to inspect residences and monitor behavior in tourist areas."
Police Lieutenant General Trairong said that within three months, the Immigration Bureau will expedite reviewing tourist data in their database. They will integrate efforts with the Center for Combating Transnational Crime and relevant agencies to establish a Joint Task Force to monitor foreigners suspected of breaking laws. In the long term, criminal databases will be consolidated into the "One Police" system, allowing police nationwide efficient access to information and tracking of offenders.
Asked whether the case impacts the Royal Thai Police's image, the spokesperson said Ming Chen Sun was not on any country's watchlist, not even his country of origin. He emphasized that many criminals worldwide conceal their identities, and many countries only become aware after incidents occur. However, once Thai police learned of this case, they acted swiftly and thoroughly. He confirmed that if evidence leads to any individual, regardless of influence or status, prosecution will proceed without exception.
