The current Chief Constable is Simon Megicks. The force is overseen by the Cambridgeshire Police and Crime Commissioner (PCC).
History & background Beginnings The origins of Cambridgeshire Constabulary date back to 1836, when the first police force within what are now the current boundaries of the force area was set up in the city of Cambridge under the name Cambridge Borough Police. This was followed in 1841 by establishment of the Isle of Ely Constabulary, covering the city of Ely, as well as Chatteris and March.
Cambridgeshire County Constabulary was formed in 1851 to police those rural parts of the county outside the jurisdiction of the Cambridge Borough Police. Huntingdonshire, the city and soke of Peterborough and the borough of Wisbech did not start their own forces until the passage of the County and Borough Police Act 1856. Wisbech Borough Police came under the authority of the Isle of Ely Constabulary in 1889. In 1949, the two forces that covered the city of Peterborough; the Liberty of Peterborough Constabulary and the Peterborough City Police merged to form Peterborough Combined Police. Cambridge Borough Police was renamed Cambridge City Police in 1951.
Mid-Anglia Constabulary to Cambridgeshire Constabulary In 1965, all five forces that exist in the Cambridgeshire area (Cambridge City Police, Cambridgeshire Constabulary, Isle of Ely Constabulary, Huntingdonshire Constabulary, and Peterborough Combined Police) amalgamated to form the new Mid-Anglia Constabulary. The force was renamed Cambridgeshire Constabulary in 1974, when the new non-metropolitan county of Cambridgeshire was created by the Local Government Act 1972 with identical boundaries to the Mid-Anglia Constabulary area.
In 2001 the constabulary conducted one of Peterborough's biggest police enquiries following the racist murder of teenager Ross Parker.ROSS PARKER TRIAL: Cold-blooded, racist murder – Peterborough Telegraph
2002 saw the Soham murders, an event that led to the biggest investigation in the history of Cambridgeshire police and one of the most expensive in the country, costing £3.5 million.Police get extra £3.5 million for Soham inquiry – Telegraph
Past and current collaboration In March 2006, as part of a review on policing nationally, the then Home Secretary Charles Clarke proposed the creation of an East Anglian force merging Cambridgeshire with Norfolk and Suffolk. While Norfolk and Cambridgeshire supported it, Suffolk would have preferred to be part of an "Eastern Coastal" force, with Norfolk and Essex. Essex, on the other hand, wanted to stay alone. However, these proposes were scrapped after a cabinet reshuffle, making John Reid the new Home Secretary.
Since 2010, the force has been collaborating with Bedfordshire Police and Hertfordshire Constabulary to form a mid-Anglia "triforce", with various departments collaborating to make local efficiencies with resources. Areas that have collaborated include Human Resources, Information Technology, Major Crime Unit, Dog Unit, Tactical Firearms Unit, Information Management Unit, Tickets and Collisions Office, Road Policing Unit, Scenes of Crime and Procurement.
There is also collaboration on a seven-force function with the adjacent forces of Norfolk, Suffolk, Essex and Kent with serious incident, counter terrorism and intelligence under the regional organised crime unit, the Eastern Region Special Operations Unit (ERSOU). Vehicle procurement is done in association with Thames Valley Police, British Transport Police and Civil Nuclear Constabulary as well as Hertfordshire and Bedfordshire under the Chiltern Transport Consortium.

Operations The head of the constabulary is Chief Constable Simon Megicks, a former deputy chief constable of Norfolk Constabulary who came into the role as chief constable in September 2025. His deputies are Deputy Chief Constable Chris Balmer, formerly a temporary assistant chief constable of the Norfolk Constabulary, Assistant Chief Constable Vaughan Lukey, Assistant Chief Constable Leighton Hammett, and Temporary Assistant Chief Constable John Massey. One notable former chief constable is the current Lord Lieutenant of Cambridgeshire, Julie Spence, who was chief constable from 2005 to 2010.
The constabulary headquarters is based in the Huntingdon suburb of Hinchingbrooke, which is home to the force executive board, information management and the force control room. The constabulary also works together with eleven police stations throughout the local policing area. They are: Cambridge (known simply as Parkside, after the street it is based on), Sawston, Ely, Cambourne, St Ives, Huntingdon town, St Neots, March, Wisbech, Hampton and Peterborough (known as Thorpe Wood, after the local nature park). It has a local police training facility in the parish of Abbots Ripton, near Alconbury (known as Monks Wood, after the local national nature reserve). Construction is underway on a new police station in Milton to meet needs no longer met by Parkside station, built in the 60s and now beyond its functional age as a police facility. The fate of Parkside station remains undecided once construction of Milton station is complete, but a move to a new city centre location is desired.
In local policing management, the force area is subdivided into two areas (also called divisions) and are known simply as North and South. Northern local policing headquartered at Thorpe Wood, covers the city of Peterborough and the district of Fenland. Southern local policing is headquartered at Parkside, and it covers the districts of Cambridge City, South Cambridgeshire, East Cambridgeshire and Huntingdonshire.
