I. PURPOSE
The purpose of this policy is to provide guidelines to police officers regarding acceptable criteria for effecting an off-duty arrest.
B.Permitted Off-Duty Arrests
When off-duty and within the legal jurisdiction of this law enforcement agency, an officer may make an arrest only when
1.The arresting officer is not personally involved in the incident underlying the arrest; and
2.There is an immediate need to prevent a crime or apprehend a suspect; and
3.The crime would require a full custodial arrest; and
4.The arresting officer possesses appropriate police identification.
C.Off-Duty Responsibilities
1.While off-duty, the police officer is responsible for immediately reporting any suspected or observed criminal activities to on-duty authorities.
2.Except as allowed by this policy, off-duty officers should not enforce minor violations such as harassment, disorderly conduct, or other nuisance offenses. On-duty personnel shall be contacted to respond to the situation where an off-duty officer becomes aware of such violations.*
3.Where an arrest is necessary, the off-duty arresting officer shall abide by all departmental policies and procedures.
D.Prohibited Off-Duty Arrests
Officers of this agency may not make an arrest off-duty:
1.When the arresting officer is personally involved in the incident underlying the arrest; or
2.When engaged in off-duty employment of a non-police nature, and the officer=s actions are only in furtherance of the interests of the private employer; or
3.When the arrest is made solely as enforcement of a minor traffic regulation.
Despite the fact that a police officer has police powers and responsibilities 24 hours a day throughout the jurisdiction, the off-duty officer should not enforce minor traffic regulations.
