Ciudad Juarez security chief Julian Leyzaola Perez said that at least a quarter of police in the violence-hit north Mexico city are involved with organized crime, reports Milenio.
The official said that bad elements remain in the force despite multiple efforts to clean it up, and that there would be a new purge to get rid of these corrupt officers. He said that some have already been fired, while others are currently being monitored.
Leyzaola is well known for his crackdown on police corruption in Tijuana, which saw murder rates fall during his time as police chief. He has faced criticism for his hardline methods, which allegedly included torturing officers accused of collaborating with criminal organizations.
