Former Chilean president General Augusto Pinochet has been charged with tax evasion by the Chilean Inland Revenue Office (offical site in Spanish). Pinochet is alleged to have made false or incomplete returns based on information brought to light by a US probe into Riggs Bank in May. The US government contends that Riggs helped Pinochet hide millions of dollars he illegally siphoned off of government accounts during his rule of Chile during the 1970s and 1980s.
Pinochet also faces charges for human rights violations during his tenure, following the revocation of his immunity in August by the Chilean legislature.
