WASHINGTON (AP) — The State Department is looking into a new reported detention of a U.S. citizen in North Korea.

North Korea’s official news agency reported Friday a 24-year old American man was detained for what it called improper behavior while he was being processed to enter the country as a tourist two weeks ago. It identified him as Miller Matthew Todd.

Department spokeswoman Jen Psaki said the U.S. is in touch with the Swedish Embassy which handles consular cases for the U.S. because Washington does not have diplomatic relations with Pyongyang.

Psaki said she does not have additional information to share about the case at this time.

North Korea’s announcement came as President Barack Obama was visiting rival South Korea.

North Korea has been holding a Korean-American missionary, Kenneth Bae, since 2012.
