East Riding of Yorkshire Constabulary
The East Riding of Yorkshire Constabulary was the territorial police force for policing the East Riding of Yorkshire from 1856 to 1968.
Formed as a result of the County and Borough Police Act 1856, it covered all of the East Riding and initially consisted of a Chief Constable, Major Bernard Grenville Layard, and 60 men.
In 1968, the East Riding Constabulary was amalgamated with York City Police and the North Riding of Yorkshire Constabulary to form the York and North-East Yorkshire Police.
