Prosecutors are asking a judge to charge the owners of a prominent Chilean financial company with bribery, tax evasion and illegally financing the campaign of right-wing politicians.

Attorney General Sabas Chahuan is seeking formal charges against Carlos Delano and Carlos Lavin, who own the Penta Group, which controls one of Chile's largest private health groups.

He's also sought charges against former tax agency officers during three days of hearings that ended Friday.

Prosecutors are asking for Delano and Lavin to be placed under house arrest while they conduct a more detailed probe.

A judge is expected to rule on whether to accept the charges within days.
