Police were startled to discover a large cache of explosives and firearms during a search of a Chinese national's residence following up on a vehicle rollover case. The suspect claims the weapons came from Rayong and were intended for self-harm, though police remain skeptical and are conducting detailed interrogations.
At 6:00 PM on May 8, 2025, Deputy Commander Ponpan Wongmanesetwat of Chonburi Provincial Police, along with investigation officers from Chonburi Province, Chonburi Forensic Unit, Na Jomtien and Huai Yai Police Stations, conducted a search of a residential property in Soi 2, Huai Yai Subdistrict, Bang Lamung District, Chonburi Province. The operation was initiated following a report from Na Jomtien Police Station about a car rollover in their jurisdiction involving a foreign driver. The suspect was identified as Ming Chen Sun, 31 years old, holding a Chinese passport and a pink Thai ID card, along with a Taiwanese woman. Military weapons were discovered in the vehicle during the initial search.
The search of the residence yielded shocking discoveries, including 4 C-4 explosives weighing 8 pounds, modified K-75 explosives, M16 firearms, 5.56mm ammunition marked LOT RTA (manufactured by the Royal Thai Army Ammunition Plant for military use), and other weapons. Mobile phone footage revealed shooting practice clips and explosive training sessions with Cambodian soldiers.
After the discovery of the large weapons cache, police cordoned off the area around the house to a 100-meter radius and called in the EOD unit to recover the explosives found inside.
During initial questioning, Ming Chen Sun stated that he previously operated a liquor shop in Cambodia but relocated to Thailand following border issues. He claimed to have purchased the weapons through a LINE group in Rayong province but could not specify the exact location. He stated his intention was to use the explosives for self-harm due to depression.
