Former US diplomat arrested in Florida is accused of serving as an agent of Cuba

Manuel Rocha, 73, who once served as ambassador to Bolivia, is accused of working to promote the Cuban government's interests

A former American diplomat who served as US ambassador to Bolivia has been arrested in a long-running FBI counterintelligence investigation, accused of secretly serving as an agent of Cuba's government, the Associated Press has learned.

Manuel Rocha, 73, was arrested in Miami on Friday on a criminal complaint and more details about the case are expected to be made public at a court appearance Monday, said two people who spoke to the AP on condition of anonymity because they were not authorized to discuss an ongoing federal investigation.
