Thai naval forces have arrested six Chinese nationals while they were attempting to illegally cross the eastern border into Cambodia, disrupting what authorities believe was a transnational criminal movement linked to cyber scam operations. The arrests took place in Chanthaburi province during the New Year holiday period, a time officials say criminal networks often exploit to evade detection, and the suspects were taken into custody for legal processing.

According to the Royal Thai Navy, the arrests occurred on 31 December 2025 in the Pong Nam Ron district of Chanthaburi. Rear Admiral Parat Rattanachaiphan, spokesperson for the Navy, said the operation was carried out by the Chanthaburi and Trat Border Defence Command in coordination with the Chanthaburi Marine Task Force. The six Chinese nationals were intercepted while attempting to leave Thailand unlawfully and travel onwards to Cambodia.

Authorities stated that the suspects were believed to be heading towards bases associated with cyber scam activities. The case highlights the continued presence of organised networks involved in cross-border human movement and technology-related fraud, which remain active despite ongoing enforcement efforts. Officials noted that the suspects appeared to take advantage of increased travel and looser conditions during the New Year holiday to avoid scrutiny.

The Navy said the incident reflects a broader pattern of transnational crime operating in neighbouring countries and using Thailand as a transit route. Such movements, officials warned, pose risks to regional security and undermine border control efforts. The arrests were described as evidence that these networks continue to adapt their methods and timing to bypass authorities.

Rear Admiral Parat confirmed that all six individuals are being treated strictly in accordance with Thai law. Their detention is being conducted under the Prevention and Suppression of Torture and Enforced Disappearance Act B.E. 2565 (2022), with authorities emphasising respect for human dignity, basic rights, and humanitarian standards. Officials have facilitated contact with relevant agencies and said all legal proceedings will be transparent and fair.

Amarin reported that the Royal Thai Navy stated that the Chanthaburi and Trat Border Defence Command, which is responsible for security along Thailand’s eastern frontier, will continue to work closely with other security agencies. Measures will be intensified to monitor, prevent, and suppress illegal border crossings. The aim, officials said, is to ensure Thailand does not become a transit route or support base for any form of transnational organised crime.
