Argentina's ex-president Cristina Kirchner was charged with corruption on Monday as a judge asked that her legislative immunity be lifted so she can be detained.
Navas, 53, has led the Prosecutor's Office as an interim since October 2017, when her predecessor, Jorge ChavarrÃa, was suspended in relation to the unfolding investigation of alleged corruption.
These criticisms of the president were included in the final report of the committee that investigated loans of more than $30 million from Costa Rican public banks to the cement importer.
Prosecutors say those arrested are part of a criminal network that manipulated board member elections in favor of people who facilitated loans to certain cooperatives.
Honduran daily El Heraldo revealed that senior police officers ordered the assassination of Honduras' top anti-drug official, ArÃstides González, in December 2009.
