High Quality Content by WIKIPEDIA articles! The Cleveland Division of Police is the law enforcement agency responsible for the city of Cleveland, Ohio. Since 2005, Michael McGrath has been the chief of police.From the early 1900s to the start of World War II, the department concentrated on managing the city's rapid growth. Cleveland was rapidly growing, even through the Great Depression, with the population increasing from 380,000 in 1900, to more than 830,000 by the 1920s. The police department grew with the city, growing from less than 400 officers in 1900, to more than 1,300 by 1920. When legendary Prohibition-era crimefighter Elliot Ness became chief in 1935, he abolished the existing system of precincts and reorganized the city into police districts, with each commanded by a captain.[1] Ness's system is still in use today. Under Ness, the police department experimented with new technologies and procedures, gaining a reputation as one of the most progressive and efficient departments in the nation.
