The decision was made by the second collegiate court of the National Supreme Court of Specialized Criminal Justice, making Toledo the first of four investigated former presidents to go to jail in Odebrecht case, one of the largest bribery and graft scandals in Latin America.

The 78-year-old former president was extradited from the United States in April last year to face charges for allegedly taking at least 20 million U.S. dollars in bribes from Odebrecht, a Brazilian construction company, in exchange for a government contract to build the Interoceanic Highway linking Peru and Brazil.

During a hearing, Toledo insisted that he was "innocent," saying that "I never made any arrangement with Mr. (Jorge) Barata," former head of Odebrecht in Peru. ■
