The West Yorkshire Constabulary (WYC) was, from 1968 to 1974, the statutory police force for the West Riding of Yorkshire, in northern England. It was formed under the Police Act 1964, and was a merger of the previous West Riding Constabulary along with six borough forces for the county boroughs of Barnsley, Dewsbury, Doncaster, Halifax, Huddersfield, Wakefield. The other four West Riding county boroughs, Bradford, Leeds, Sheffield and Rotherham, retained independent police forces (a merged force for Sheffield/Rotherham).
