The Wakefield Borough Police came into being in September 1848 after the Borough Council were tasked with forming a 'constabulary force' for the newly formed borough [REF].
The city boundaries increased in size and with this, Wakefield City Police absorbed 279 acres from the West Riding Constabulary when the Wakefield City Extension Act came into force - this included the area of Thornes; the site of where Pinderfields Hospital now stands and parts of Lupset and Flanshaw.
