WASHINGTON — A U.S. Navy sailor has been detained in Venezuela after traveling on personal business, officials said Wednesday. 

A defense official said in a statement they are aware of reports that Venezuelan law enforcement detained a sailor around Aug. 30 while on personal travel.

The official said the Navy is looking into the situation and working with the State Department.

U.S. State Department spokesperson Matt Miller said the department was tracking the service member’s detention and monitoring the situation, but did not provide further details.

The detention follows a similar disappearance earlier this year when a U.S. Army soldier was arrested after traveling to Russia to visit his girlfriend.

Staff Sgt. Gordon Black, 34, is still in Russia and was sentenced in June to three years and nine months in prison after his girlfriend accused him of stealing from her.

Black remains an active duty member of the U.S. Army but was placed in confined civilian authority status in May, which is a non-pay status, the Army said in a statement to the AP.

Last week, the attorney for Travis King, another Army private who fled to North Korea last year, said that King will plead guilty to desertion and four other charges and take responsibility for his conduct. King will be given an opportunity at a Sept. 20 hearing at Fort Bliss, Texas, to discuss his actions and explain what he did.

In December the United States freed a close ally of Venezuelan President Nicolás Maduro in exchange for the release of 10 Americans imprisoned in the South American country and the return of a fugitive defense contractor known as “Fat Leonard” who was at the center of a massive Pentagon bribery scandal.
