The number of arrests for drug smuggling and manufacturing in South Korea has significantly increased in the first eight months of 2026, according to police data released on October 5, 2026. The National Office of Investigation (NOI) reported a 33.8% year-on-year rise in arrests for these offenses, with 174 individuals apprehended between January and August.
Overall drug-related arrests also saw an increase, with a 5.3% rise to 9,530 individuals caught. Arrests for drug dealing specifically went up by 6.6% to 3,396, while offenses involving medical drugs saw an 11.9% increase, resulting in 706 arrests.
Police efforts have focused on dismantling drug supply sources and distribution networks. A notable case involved the repatriation and arrest of alleged drug kingpin Park Wang-yeol from the Philippines. Park is suspected of distributing drugs to South Korea and is also implicated in the deaths of three South Koreans. Authorities identified approximately 6.3 billion won (US$4.69 million) worth of drugs and 8.63 billion won in criminal proceeds linked to him.
Further action led to the arrest and repatriation of Choi Byeong-min, identified as a key supplier for Park, with the assistance of Thai authorities. This operation uncovered 41 additional offenses and led to the seizure of 6 billion won in criminal proceeds before indictment.
The NOI stated its intention to enhance cooperation with domestic and international agencies, including plans to host an international narcotics conference next month.
