Saca – who was president of the Central American country from 2004 to 2009 – faces prosecution for money laundering and establishing a criminal association, among other charges, according to a police statement.
According to prosecutors, Saca has not clarified the origins of $5 million of the $6.5 million in assets he acquired during his time in office.
Saca, a former radio sports announcer, declared his fortune at $3.6 million when he took office. Five years later, it had grown to $13.1 million.
Sidney Blanco, the chairman of the ethics commission of the highest court, made serious accusations against Saca in a television interview last week.
Blanco said the 59-year-old was responsible for the misappropriation of state money during his time in office.
Also under investigation for corruption, is the former President Mauricio Funes, who succeeded Saca.
