An American civilian who worked at the U.S. military in South Korea has been indicted on charges of trafficking drugs to Yongsan Garrison in central Seoul, prosecutors said Friday.

The Seoul Central District Prosecutors' Office said the 35-year-old, identified only by his initial J, is suspected of receiving 35 pills of MDMA, better known as "ecstasy," and 20.5 grams of hemp from an unidentified seller last year.

Still, the suspect was not taken into custody.

The drugs were sent from the Netherlands and went through the distribution center for military posts at Incheon International Airport, Seoul's main gateway, before arriving at the military base, prosecutors said.

The suspect, who worked with the 8th U.S. Army, was fired in September after being caught by South Korean police who received a tip from the U.S. military's criminal investigation division. (Yonhap)
