An American imprisoned in Cuba for nearly three years is suing his former Maryland employer and the United States government for $60 million, saying they didn’t adequately train him or disclose risks he was undertaking by doing development work on the Communist island.

Alan Gross and his wife Judy sued Friday in federal court in Washington. The lawsuit alleges that the economic development company Gross was working for in Cuba and the U.S. government, with which the company had a contract, failed to provide Gross “with the education and training that was necessary to minimize the risk of harm to him.”
