The Brookhaven Police Department is tasked with serving and protecting the city. The department strives to partner with the community in maintaining safety and order in the city. This includes creating partnerships with residents, businesses, community organizations, schools and other groups. It is the responsibility of every member of the Brookhaven Police Department to strengthen the affinity between the residents of Brookhaven and the police service. The department's role is to enforce the law in a fair and impartial manner, recognizing both the statutory and judicial limitations of police authority and the constitutional rights of all persons.
One of the goals of the city’s creation was to increase public safety presence. On July 31, 2013, the Brookhaven Police Department launched patrols. The department is comprised of the patrol department, which answers calls for service and provides proactive patrols; the criminal investigations division, which investigates all crimes and manages internal affairs; and the support service division, which includes special units, neighborhood watch and other traffic enforcement.
