The Cambridge University Constabulary is a body of constables that patrol the precincts of the University of Cambridge. There are approximately 20 to 30 constables in the constabulary.[1] The university constables are commonly known as 'bulldogs'. In reality, the constabulary acts as a security and stewarding service for the university with policing the responsibility of Cambridgeshire Constabulary; the university constabulary made no arrests between 2010 and 2015 and may not have made any in the previous ten years either.[2]
