Police Reveal Chen Ming Sun as Boss-Level Cambodia Scam Gang Leader, But Not on International Watch List
Police identified Chen Ming Sun as a high-level leader of a Cambodia-based scam and call center gang, though he holds no international alerts despite financial links to fraud networks across Southeast Asia.
On May 14, 2025, Pol. Lt. Col. Trairongth Phiwphon, spokesperson for the Royal Thai Police, disclosed progress in the Chen Ming Sun case, revealing that investigators have uncovered financial trails linking the suspect to scammer and call center operations in Cambodia. Deputy Police Chief Pol. Gen. Samran Nualma has ordered the Cyber Police to expedite the investigation and collect evidence from all angles, with officials currently analyzing financial pathways, personal connections, and immigration records to establish links to broader online criminal networks.
Based on preliminary investigation data, authorities confirmed that Chen Ming Sun is not a low-level operative within the call center gang, as fraud victims typically refer to such Chinese nationals as "bosses." However, the exact level of his involvement requires further analysis. The national police headquarters is taking the case seriously, with Police Chief Pol. Gen. Kittirat Panpetch having personally conducted initial inspections and assigning Deputy Chief Pol. Gen. Samran to closely oversee the investigation. Thai police have been coordinating continuously with Chinese authorities.
Joint intelligence checks between Thailand and China revealed that Chen Ming Sun has no listing on international watchlists or suspicion alerts in his home country, prompting Thailand to review and strengthen its foreign national screening and surveillance measures. The police are advancing the "One Police" initiative to integrate databases across all agencies, facilitating foreign national checks nationwide. Additionally, the Royal Thai Police is receiving cooperation from LINE Thailand in blocking illegal chat rooms and websites related to online gambling, drug trafficking, weapons sales, and exploitation of children and women. LINE Thailand has shut down over 50% of the illegal accounts and groups reported by police, and authorities are requesting that LINE elevate its proactive detection system to instantly block "flesh rooms" and online scam groups while forwarding data for prosecution. Police also warned the public that joining LINE groups or platforms involved in illegal activities risks falling victim to fraud and potential legal prosecution.
