A former American diplomat who served as a U.S. ambassador to Bolivia has been arrested and accused of secretly serving as an agent of Cuba’s government, according to The Associated Press. Officials say Manuel Rocha, 73, was arrested in Miami on Friday on a criminal complaint. According to sources, more details about the case are expected to be made public at a court appearance Monday. One of the two people who came forward with the complaint said the Justice Department case accuses Rocha of working to promote the Cuban government’s interests.
