A South Korean man wanted under an Interpol Red Notice has been arrested by Thai immigration police at a restaurant in the RCA Royal City Avenue) nightlife district of Bangkok. The suspect, identified only as Mr Kim, was found allegedly inhaling nitrous oxide, commonly known as laughing gas, along with other patrons during the operation. Authorities said he had overstayed his permission to stay, after entering Thailand while evading arrest in South Korea.

The arrest took place on 24 April 2026 after Immigration Bureau Division 1 officers, under the direction of Pol Lt Gen Phanumart Boonyalak, launched an investigation into reports that a transnational criminal was hiding in the area. Officers went undercover as customers inside a Korean restaurant, where they observed both Thai and South Korean patrons inhaling nitrous oxide from balloons. Mr Kim was identified at the scene and immediately apprehended.
Police confirmed that Mr Kim is listed on an Interpol Red Notice for offences related to online fraud and scam operations and is considered part of a major criminal network sought by South Korean authorities. Investigators also found that his permission to remain in Thailand had expired, placing him in overstay status at the time of arrest.
During the raid, officers also detained a Thai national, identified as Mr Ek, the restaurant manager. Authorities seized evidence including 17 ten-litre tanks of nitrous oxide disguised with cartoon designs, 10 smaller two-litre canisters and a large quantity of balloons used for inhalation. Mr Ek faces charges of selling a medicine without a licence under the Drug Act BE 2510, as nitrous oxide is classified as a substance affecting human health.
Police also revealed that the establishment was using bank accounts belonging to South Korean nationals to receive payments for the service. Further investigations are underway to identify and prosecute additional individuals involved in the operation.
The Immigration Bureau has urged the public to report suspicious behaviour involving foreign nationals or activities posing a risk to society. Tips can be submitted via the 1178 hotline, which operates 24 hours a day.
Naewna reported that Mr Kim will face legal proceedings in Thailand for immigration violations before being extradited to South Korea to face charges under the Interpol Red Notice. Authorities said enforcement efforts against transnational crime networks operating in Thailand will continue.
