The Seoul Serious Crime Investigation Agency’s narcotics bureau transferred a Southeast Asian national identified only as A in custody to the Incheon District Prosecution Office on 23 October 2026 on suspicion of violating the Narcotics Control Act.[1][2] Investigators made the emergency arrest through controlled delivery, delivering the customs-intercepted drugs normally to track the actual recipient.[1]

The agency applied for a detention warrant on 17 October because of the scale of the smuggling and risk of evidence destruction and flight, the prosecution office requested it the next day, and the court issued it the same day for those reasons.[1] The transfer was the agency’s first case of handing a detained suspect to a prosecution office since its launch.[3][2]

In its first-month tally, the Seoul office counted three drug cases among four total transfers to the prosecution service, including this 23 October cannabis transfer.[4]
