Auxiliary police, also called Special Police, are usually the part-time reserves of a regular police force. They may be armed or unarmed. They may be unpaid volunteers or paid members of the police service with which they are affiliated. In most jurisdictions, Auxiliary Police officers are empowered to make arrests for crimes that occur in their presence.
