Fox News reports that North Korea announced that it has detained an American for "improper behavior."

The official Korean Central News Agency has identified the tourist as Miller Matthew Todd who entered North Korea on April 10.

The 24-year-old entered the country with a tourist visa, but reportedly tore it up and shouted that he wanted to seek asylum.

The Agency has reported that Miller Matthew Todd (the surname may have been placed first) chose North Korea "as a shelter."

New York Daily News reports that Miller was detained for "gross violation" of North Korea's legal order and was currently being investigated. No further details were given.

U.S. State Department spokewoman Jen Psaki told reporters on Friday that the U.S. is aware of the report, but she did not confirm whether an American was actually being held or not.

The department is reportedly in contact with the Swedish Embassy, which handles consular cases for the U.S.

Psaki emphasized, "There is no greater priority to us than the welfare and safety of U.S. citizens. We don't have additional information to share at this time."

The announcement of the detainment came while President Barack Obama was visiting South Korea.

Both the U.S. and South Korea have become aware of North Korea possibly following through with a fourth nuclear test.

North Korea is known for its incredibly strict practices when it comes to detainment.

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

Although Bae's family and the U.S. State Department have called for his release numerous times citing his failing health, a release has yet to happen.
