Colombian prosecutors have opened an investigation into allegations of election fraud involving the former chief of the secret police.
Jorge Noguera is accused of rigging national elections in 2002 in favor of Colombian President Alvaro Uribe.
Noguera is the former director of the DAS (Colombia's equivalent of America's FBI), who left the security agency last year after being accused of collaborating with right-wing paramilitaries.
Earlier this year, Noguera was appointed Colombia's consul general in the Italian city of Milan. He has denied accusations of wrongdoing.
Mr. Uribe is running for a second four-year term as president in elections on May 28.
