Leicestershire Police is the territorial police force responsible for policing Leicestershire and Rutland in England.
Leicestershire Police was formed in 1839. In 1951 it amalgamated with Rutland Constabulary to form Leicestershire and Rutland Constabulary and in 1967 merged with Leicester City Police to form Leicester and Rutland Constabulary. After the Local Government Act 1972 came into force in 1974 it was renamed Leicestershire Constabulary. In 2012 it changed to Leicestershire Police to be 'in keeping with modern policing'.
