MEXICO CITY (Reuters) - The head of Mexico's organized crime unit stepped down on Thursday, just weeks after announcing that members of his team had been charged with having links to the nation's most powerful drug cartel.
Jose Cuitlahuac Salinas, head of the unit in the attorney general's office, resigned for "personal reasons," a spokesman for the office said.
