There are two police departments in the city , the Police of the City of Monterrey ( locally known as the '' Policía Regia '' ) , dependent on the municipal government , and the State Public Safety . The '' Policía Regia '' protects the city 's downtown and main areas , while the State Public Safety is in charge of remoter areas . Since the 2011 attack on the Casino Royale , security has been reinforced by military and federal police
