Town constables were appointed starting in 1801. A Police Commission was established in 1861 but the first forty officers did not begin work until 1865. In 1921, the Detroit Police Department became the first police department in the country to utilize radio dispatch in their patrol cars. A historical marker at Belle Isle Park describes the new advancement in technology. In 1893, the department hired its first female officer and its first Black officer. The Detroit Police Department established a Women's Division in 1921 that was tasked with cases of "child abuse, sexual assaults, juvenile delinquency, and checking establishments for illegal minors." Female officers were not allowed to work on criminal cases unless accompanied by male officers until 1973, after a series of discrimination lawsuits prompted changes in department policy. In February 1940, Mayor Richard Reading, the Superintendent of Police, the county sheriff and over a hundred more were indicted on corruption charges. The Mayor was accused of selling promotions in the department. Eighty officers were accused of protecting illegal gambling operations in the city. In the end, the Mayor served three years in jail, ending in 1947. In 2000, the Detroit Free Press published a series of articles after a four-month investigation into fatal shootings by Detroit police officers. At the time, Detroit had the highest rate of police-involved shootings of any large city in the United States, surpassing New York, Los Angeles, and Houston. The city requested an investigation by the United States Department of Justice into the department's handling of deadly force incidents. By 2001, the Justice Department's investigation had uncovered issues with the department's arrest and detention practices as well. Between 2003 and 2014, the Detroit Police Department was placed under federal court oversight by the Justice Department as the result of allegations about excessive force, illegal arrests and improper detention. This process cost the city of Detroit more than $50 million. By 2014, the department's use of force had been "seriously reduced" and the U.S. District Judge overseeing the case stated that the Detroit Police Department had "met its obligations" for reforms. In 2005, the department's thirteen precincts were consolidated into six larger districts as a cost-cutting measure. The department restored a number of precincts in 2009 after citizens complained about the change. In 2011, it was announced that the Detroit Police Department would be reverting to the original precinct structure, with officials citing "gap in services" and concerns over the new command structure. On June 11, 2010 it was reported that the City of Detroit would acquire the former MGM Grand Detroit temporary casino building on John C. Lodge Freeway for $6.23 million and convert it into a new police headquarters complex which would also house a crime lab operated by the Michigan State Police. The renovated building also houses the Detroit Fire Department headquarters. The former casino building has of space. The historic Detroit Police headquarters is in Greektown. On June 28, 2013, the new public safety headquarters opened for business.
