The duties of the Patrol Division are to deter and investigate criminal activity, solve community related problems in a collaborative effort with the community, conduct traffic enforcement and accident investigation, and provide for the care and control of animals.

The division consists of over 174 employees who work in a fast paced, dynamic environment to accomplish the delivery of police services to the citizens of the City of Thornton. Patrol Officers are assigned to geographical areas of responsibility, referred to as "police districts", to preserve and protect the security and safety of persons and property. District Officers respond to radio dispatch calls for service to intervene in and investigate citizen complaints, crimes in progress, crimes reported after they have occurred, traffic accidents, disturbances and a multitude of other community related service requests. During the course of their duties District Officers engage in conducting preliminary investigations, provide for the protection and preservation of crime scenes, collect evidence, interview witnesses, victims and suspects, complete detailed reports, conduct follow up investigations, conduct proactive patrols, make arrests, and facilitate problem solving efforts with members of the community.
