Peruvian prosecutors have opened an investigation into former President Alejandro Toledo's administration.
Mr Toledo left office earlier this year
Attorney General Adelaida Bolivar said her office was gathering information about several corruption scandals that arose during Mr Toledo's presidency.
In September, Congress voted to form a committee to investigate allegations of mishandling of funds involving the former president, his wife and aides.
Mr Toledo, who was president between 2001 and 2006, denies all the charges.
"We are gathering information and we are investigating, but this is a preliminary investigation," Ms Bolivar told reporters.
Mr Toledo, who left office in July, was dogged during his five-year term by a series of scandals involving his wife Eliane Karp, close aides and his siblings, correspondents say.
