In an effort to step up the fight against corruption and organized crime, the Mexican government has changed 284 chiefs of the federal police (PFP), an official said Monday, according to dpa. The PFP, with more than 20,000 agents, is among the most important Mexican agencies responsible for fighting the illegal drug trade and also controls federal roads and customs, Federal Public Security Minister Genaro Garcia Luna said. The decision to change the police leadership was unexpected, and it includes the top 34 PFP commanders in each one of Mexico's 32 states. Mexico City and Veracruz each have two top commanders. Garcia Luna said in a press conference that the new appointees received special training ahead of the change.
