SEOUL, South Korea (AP) -- South Korea's government says a South Korean student from New York University has been released by North Korea after about six months of detention.
Seoul's Unification Ministry said Monday that North Korea repatriated Won Moon Joo, 21, at the border village of Panmunjom. Joo had been arrested for crossing the Chinese border into North Korea.
South Korea's National Intelligence Service said it will investigate whether Joo violated the country's anti-North Korean security law, which prohibits unapproved travel to the North.
Joo has permanent resident status in the United States. The exact motivation for his entrance to North Korea wasn't clear.
