The Baltimore County Police Department is the primary law enforcement agency for Baltimore County, Maryland. They have been accredited by Commission on Accreditation for Law Enforcement Agencies (C.A.L.E.A.) since 1984.

Police chief[edit]

The current Chief of the county police department is Terrance Sheridan.

In March 2017, James Johnson retired. Terrence B. Sheridan returned to take over control of the police department.[1]


1874: The Baltimore County Police Department was established by the General Assembly of Maryland on April 11, 1874. The Maryland state legislature approved what became Chapter 374 of the Laws of Maryland. This authorized the Board of County Commissioners for Baltimore County "to appoint such number of policemen as they may deem necessary, for the better protection of persons and property; the number not to exceed thirty at any one time, and to designate such number of said policemen as they may deem advisable, not exceeding five, as chief policemen."

A second provision stated that "the pay of each policeman shall be two dollars per day, except such police as may be mounted; and mounted policemen shall furnish their own horses, trappings, equipments and forage for horses, and the pay of the mounted policemen shall be three dollars per day." On June 17, 1874, the County Commissioners divided the two mile (3 km) portion of the county bordering the Baltimore City boundary into five districts and appointed the first police force. Officers were appointed to one year terms.

1878: County Commissioners were authorized to build a station house at Waverly. The Canton Station was added a year later. Both communities were absorbed into the adjacent City of Baltimore, the first at the second major annexation of 1888 and the second in the third annexation of 1919

1883: a new position was created, "Marshal of Police", (a title then also used on the city force, the Baltimore City Police Department since its reorganization and supervision by the Governor of Maryland in 1860). Charles O. Kemp was appointed to this office. Kemp, a loyal Democrat, had been the Superintendent of the Baltimore County Almshouse, (now the site of the Historical Society of Baltimore County). He had served as a trustee for one of the schools in the Fifth District. The new position consolidated the responsibility and control of the police force under one person instead of individual chiefs for each police district.

1885: The first call boxes were installed in the area around Huntington Avenue (later renamed 25th Street) in the Harwood neighborhood, south of Waverly, North Avenue, (then also known as Boundary Avenue - the former city limits of 1816-1888), near Jones Falls, and 28th Street (also in Waverly, off Greenmount Avenue/York Road).

1886: A new station was built in Mount Winans, (also now in the southwest portion of the City since 1919).

1888: A 17-square-mile (44 km2) portion of Baltimore County was annexed by Baltimore City. The number of officers in the Baltimore County Police Department was cut from 33 to 10 as officers and station houses were absorbed into the Baltimore City Police Department (originally organized as a nightwatch and constables in 1784, reorganized under supervision of the Governor of Maryland in 1860) on the western and northern "precincts" adjacent to the City. The heavily industrial and residential communities on the east such as Highlandtown and Canton voted against annexation in the referendum and stayed in the County until 1919.

1891: B.Co.P.D. Stations were built at Govans and Arlington.

1892: The Mount Washington Station opened.

1894: Terrence Doyle became the first county police officer to be shot when he attempted to arrest two men for breaking into a barn. Doyle was shot six times, but none of the wounds proved serious and he recovered. The two suspects were apprehended.

1902: The Maryland General Assembly passed an act aimed at improving the background of those appointed to the Baltimore County police force. The act stated: "all appointments hereafter made to the police force of Baltimore County shall be made from the qualified voters thereof, and all applications for such appointments shall be made upon printed blanks to be furnished free of charge by the County Commissioners, wherein the applicant shall set forth in his own handwriting his full name and age, the place and State of his birth, his occupation for two years preceding his application, and such other information as the Commissioners may require touching the merit and fitness of the applicant for the position for which he applies; such application shall be signed by the applicant, with his affidavit that the facts therein set forth are true to the best of his knowledge and belief, and shall contain blanks to be filled in by four reputable citizens of said County, certifying that the applicant is known to them for not less than one year and in character and habits, to the best of their knowledge and belief is in all respects fit for service which he wishes to enter. All appointments shall be hereafter made from applications filed not less than one month or more than two years previous to such appointments; such appointee shall not be less than 21 years nor more than 45 years of age; all officers shall be retired from service at an age not exceeding 58 years."

1903: Invented in 1876 by Alexander Graham Bell and installation began in the City two years later with the organization of the Maryland Telephone Company. Telephones were placed in the Arlington, Mount Winans, and Canton police stations. County Commissioners approved the purchase of a patrol wagon not to exceed the cost $265.

1912: Officers were granted twelve days of leave per year. Prior to this, officers were on duty seven days a week.

1913: The first female was appointed to the county police force as a matron. Two other women, Eva Aldridge and Ruth Jones were appointed to summer positions as Special Officers to protect young girls at the river resorts along the Patapsco River, Back River and Middle River in the eastern part of the county along the Chesapeake Bay.

1916: The first patrol automobile was purchased and the first motorcycle was also put into service.

1919: Another 40 square miles (100 km2) of suburban and rural Baltimore County was annexed by Baltimore City in the third major annexation after a long political campaign since 1914, cresting in 1918 in the state legislature voting. Baltimore County loses this time 34 of its 43 officers to the Baltimore City Police Department. The Canton, Arlington, Mount Winans, and Gardenville stations also became part of the city forces as of January 1, 1919.

On 7/5/2018, it was announced intradepartmentally that the uniforms worn by patrol officers will change to a “more contemporary look”. The new uniform changes have not been made public yet, but it is speculated that it will be based upon a similar style worn by Montgomery County Police. The notable changes will be 5.11 blue cargo pants and molle style external vest carriers. The “class A” white shirt with dress blouses and striped blue pants will not change. On 1/11/2019, the new uniform and Police Interceptor Utility was officially unveiled and are currently being transitioned into the fleet.


Formerly known as "police stations", since the 1970s Baltimore County has been divided into ten police precincts.  Number 5 is intentionally skipped and will be used if the department needs to expand at a later time.  Most recently, this happened in 2006 when Precinct 4 opened in Pikesville and Precinct 3 moved from Garrison to Franklin.  Former Precincts 10 (Fullerton) and 13 (Edgemere) were absorbed into Precincts 9 and 12, respectively.

Baltimore County Police Eurocopter AS350 at the famous historic College Park Airport's 100th Anniversary in College Park, Prince George's County.

The primary patrol vehicles used are the Ford Taurus, Ford Interceptor Utility and some remaining Crown Victorias. Both Dodge and Chevrolet vans are used for prisoner transport. Motorcycle units ride Harley-Davidson Road Kings. The department recently placed 3 new Eurocopter AS350B3 helicopters into service.

In early 2014, the department announced that they would begin to phase out the aging & discontinued Ford Crown Victoria with new Ford Taurus police interceptors. Beginning sometime between fall 2018 and early 2019, Baltimore County Police will replace all remaining Crown Victorias and older Tauruses with the Ford Explorer Police Interceptor Utility. The new Explorers are expected to be on the road by early 2019. As of September, 2018, the VOM Shop Located in Hunt Valley has started to receive the first 250 Explorers and are being outfitted to be on the street by 2019.


The primary duty firearm is the Glock 17 chambered in 9mm issued with Ameriglo 3 dot night sights, and a TLR-7 weapon mounted light. The Remington 870 shotgun is issued to every marked patrol car, except specialized units like K9, BPI, and the Traffic units/Crash Team to name a few. Axon X2 Tasers, and Less Lethal beanbag shotguns AR-15 patrol rifles as well as M16 patrol rifles are issued to some specifically trained officers. All officers are issued OC spray and an ASP baton. Officers working in a uniformed capacity excluding Tactical (SWAT) are issued Axon Flex 2 Body Cameras and issued phones linked to them.

The 870s, some of which date back to the 1980s, are slated for an upgrade that includes their own mounted lights, rails for optics, ghost ring sights and retractable stocks.

In October 2018, after significant review of the performance and reliability history of the FNS-40LS, the Baltimore County Police Department will be transitioning to the Glock 17 chambered in 9mm starting January 2019 and span over a two month transition period.

Prior to the FNS-40LS officers were armed with the SIG Pro SP2340 in .40 S&W, prior to the SP2340 was the SIG-Sauer P226, after the transition in the 90s from S&W Model 10 Revolvers.
