In 1972, the Hillcrest area police departments joined together to form a law enforcement partnership known as the Suburban Police Anti-Crime Network (S.P.A.N.). Currently, the members of S.P.A.N. are Highland Heights, Richmond Heights, Mayfield Village, Mayfield Heights, and Lyndhurst Police Departments. S.P.A.N. shares training and resources to maximize law enforcement and crime prevention services while reducing costs to each city. S.P.A.N. specialized law enforcement units consist of Traffic Accident Investigation Unit, S.W.A.T. tactical teams, Drug Enforcement Unit, Bomb Squad, Hostage Crisis/Negotiation, and Drug Enforcement Unit.
