North Korea says it has arrested a US student accused of committing a "hostile act" against the state.
The KCNA state news agency said the US government had "tolerated and manipulated" the student, who attends the University of Virginia.
The unnamed student had entered North Korea as a tourist, it said, and "aimed to destroy the country's unity".
KCNA did not give further details, but said the student was now under investigation.
An official at the US embassy in the South Korean capital, Seoul, told Reuters news agency that it was aware of the arrest.
The student is the third Western citizen known to be held in North Korea.
A Canadian pastor and a Korean-American man are also being held by the secretive East Asian state.
