Prosecutors in El Salvador say police have arrested former President Tony Saca for alleged illicit enrichment, unlawful association and money laundering.

Saca held office from 2004 to 2009 for the rightist Nationalist Republican Alliance.

Police said Saturday that six former officials in his government were also arrested.

Prosecutors say Saca has not clarified the origins of $5 million of the $6.5 million in assets he acquired during his time in office.

Saca is a former radio sports announcer. He declared his fortune at $3.6 million when he took office. Five years later, it had grown to $13.1 million.

Former President Mauricio Funes who succeeded Saca is also under investigation for corruption, as is former President Francisco Flores.
