Security police are those persons, employe by or for a governmental agency, who provide police and security services to their properties. Security police may have limited arrest authority and they may or may not be able to enforce local laws depending on local law and agency policy. They generally protect their agency's facilities, properties, personnel, users, visitors and operations from harm and may enforce certain laws and administrative regulations. Security police may be endowed with full police powers of crime prevention, arrest, law enforcement and investigation within their jurisdictions and often nationwide.
