Mexican Attorney General Arturo Chavez Chavez has resigned.
President Felipe Calderon announced Chavez's resignation Thursday, but gave no reason for the decision.
Chavez had faced criticism from women's groups that said he did little to prevent or solve rapes and murders of hundreds of women while he served as attorney general of the state of Chihuahua.
President Calderon has nominated Marisela Morales to replace Chavez. The nomination must be approved by the Mexican Senate. If approved, she would be the first woman in the job.
