South Korean Police Arrest Thirty Suspects in Major Southeast Asian Drug Ring

Police estimated that the seized methamphetamine could produce about 410,000 doses, while the ketamine could produce roughly 160,000 doses, underscoring the scale of the operation.
In a separate case, a suspect identified as B allegedly collected 2,000 yaba tablets smuggled from Thailand, hid them in snack boxes and distributed them to Thai nationals living in South Korea.
Police said a suspect identified as C recruited a relative or hometown junior as a courier and concealed etomidate in a cosmetic container to smuggle it from Thailand through Incheon International Airport.
The suspects were accused of operating over an extended period, from June of last year through April of this year or the month before the police announcement, rather than in a single smuggling incident.
Police said the investigation was enabled by cooperation with the National Intelligence Service and Customs, which supplied information that helped investigators make sequential arrests.
South Korean police arrested 30 people in a major regional drug-smuggling operation involving narcotics from Southeast Asia. The raids uncovered methamphetamine, ketamine, yaba tablets and etomidate worth approximately 6 billion won ($4.3 million), along with 27.45 million won in suspected criminal proceeds Yonhapnews. The seized methamphetamine could produce roughly 410,000 doses, while ketamine could yield about 160,000 doses, according to Yonhapnews.
Smugglers used creative hiding methods to bring narcotics through borders. According to Yonhapnews, couriers concealed drugs inside sunflower-seed packets, snack boxes and cosmetic containers. Some taped narcotics directly to their bodies before traveling. One suspect allegedly hid 2,000 yaba tablets in snack boxes sourced from Thailand, then distributed them to Thai nationals living in South Korea Yonhapnews.
Another courier recruited by a suspect concealed etomidate—a powerful sedative—inside a cosmetic container and smuggled it from Thailand through Incheon International Airport Yonhapnews. Once drugs entered South Korea, distributors used "dead drop" locations to hand off packages to buyers without meeting face-to-face.
The operation spanned from June of last year through April of this year, according to Yonhapnews, rather than occurring in isolated incidents. Police identified 17 suspects detained, including seven smugglers, 13 distributors and 10 buyers or users Yonhapnews. Three overseas ringleaders remain at large, with Interpol red notices issued for them. Authorities are pursuing an international investigation to identify at least one additional suspect.
The National Intelligence Service and Customs agency played crucial roles in breaking the network. Yonhapnews reported that these agencies supplied critical information that enabled sequential arrests. Cooperation between police, intelligence officials and border authorities allowed investigators to identify patterns and track suspects across the supply chain. The coordinated effort demonstrates how multiple agencies working together can dismantle large-scale smuggling operations.
Cambodia, the Philippines and Thailand emerged as primary sources for the confiscated narcotics. Yonhapnews reported that drugs flowed from multiple Southeast Asian countries into South Korea through smuggling networks. The region remains a major production and transit hub for methamphetamine, ketamine and other synthetic drugs destined for East Asian markets. The scale of this bust underscores the ongoing challenge of controlling transnational drug trafficking across Asia.
