Pattaya, Thailand – A Chinese national detained in connection with a major military and explosives weapons seizure in Pattaya has been transferred out of the intensive care unit into a regular hospital room, although under 24/7 heavy guard, after his condition stabilized, authorities confirmed on Monday.
Mingchen Sun, 31, was moved from the ICU to a heavily guarded private ward at a Pattaya Hospital following an improvement in his health, according to the Department of Corrections.
Sun faces pending trial on serious firearms and explosives charges after police uncovered a large cache of military grade weapons at a rented house linked to him earlier this month. The discovery followed a traffic accident in Na Jomtien that caused officers to search the property, where they reportedly found assault rifles, grenades, explosives, ammunition, and materials used for bomb-making.
Investigators are exploring possible connections between Sun and broader transnational criminal networks, including Cambodian-based scam syndicates.
The suspect remains under strict 24-hour supervision by a joint team of corrections officers, Banglamung police, and special operations units to prevent any attempt to escape. In person visits and internet use continue to be prohibited.
Sun was urgently taken to a hospital on May 11th after suffering convulsions and losing consciousness shortly after his arrival at Pattaya Remand Prison. Initial drug screenings returned negative results for methamphetamine and cannabis. Medical staff believe the episode was triggered by an overdose of prescribed medication he had taken prior to entering custody. He is also known to have a history of depression.
Corrections spokesperson Yutthana Nakruangsri said Sun has now regained consciousness and is showing signs of steady recovery. Doctors expect him to begin consuming small amounts of food in the coming days.
Further blood tests for alcohol, benzodiazepines, and pesticides are still underway, with final results anticipated within 5 to 15 days.
The case has drawn significant attention due to the scale of the weapons haul and its potential links to organized crime operating across borders in Southeast Asia.
