Considered to be one of Mexico's most successful but controversial police chiefs, Julian Leyzaola, of Ciudad Juarez, has been summoned to appear before a judge.

While Leyzaola has not been criminally charged, the human rights prosecutor for Baja California state has accused him of crimes including torturing suspects to get information.
