Brazil was alleged intended recipient of US couple’s nuclear submarine secrets

Jonathan and Diana Toebbe are accused of trying to sell secrets to Brazil, which cooperated in an FBI operation against them

The country that an American spy couple tried to sell nuclear submarine secrets to last year has been revealed to be Brazil.

Jonathan and Diana Toebbe, a suburban couple who lived in Annapolis, Maryland, were arrested last October and charged with attempting to sell the design of US nuclear-powered submarines to someone they thought was a representative of a foreign power - but who turned out to be an undercover FBI agent.
