Three police officers and two other men were arrested on suspicion of working for a drug cartel in central Mexico, federal authorities said Sunday. The former state security chief and the police chief of the state capital were detained for questioning. Investigators uncovered the alleged police corruption ring after the arrest earlier this month of 14 alleged members of the Beltran Leyva drug cartel in Cuernavaca, the capital of Morelos state, the Public Safety Department said in a statement. The head of the Morelos police vehicle recovery unit was arrested for allegedly selling stolen cars and auto parts to the cartel, the statement said, while a former state police officer was arrested on suspicion of serving as a hit man. Two Cuernavaca municipal police officers were accused of stealing cars and kidnapping for the Beltran Leyva gang, and a fifth suspect was also arrested as an alleged hit man.
