England - Nottinghamshire Police patch

Nottinghamshire Police is the territorial police force responsible for policing the shire county of Nottinghamshire and the unitary authority of Nottingham in the East Midlands of England. The area has a population of just over 1 million.
Nottinghamshire Constabulary was established in 1840. The following year it absorbed Retford Borough Police. In 1947 it absorbed Newark-on-Trent Borough Police. In 1968 it amalgamated with Nottingham City Police to form Nottinghamshire Combined Constabulary. On 1 April 1974 it was reconstituted as Nottinghamshire Police under the Local Government Act 1972, but retained the name Nottinghamshire Constabulary on all signage, uniform and vehicles until the early 21st century.
