The U.S. Army has charged Private Travis King with crimes ranging from desertion for running into North Korea in July to assault against fellow soldiers and solicitation of sexually explicit materials involving minors, according to some documents.

The Army's case against King, which has not been previously reported, includes eight distinct charges under the Uniform Code of Military Justice, setting up a substantial legal battle for the 23-year-old soldier after his release from North Korean custody in September.

The Army did not immediately respond to a request for comment.
