Welcome to the Hertfordshire Constabulary official LinkedIn page. Please do not use this page to report crime. Non-emergency 101 - in an emergency always dial 999. Hertfordshire Constabulary is the territorial police force responsible for policing the county of Hertfordshire in England. Its headquarters is in Welwyn Garden City. The force is headed by Chief Constable Charlie Hall and its manpower consists of over 3,300 police officers and staff, supported by more than 300 Special Constables. The Constabulary was founded in 1841, under the County Police Act, five years after the Hertford Borough Police and St Albans Borough Police had been formed. In 1889, the Hertford Borough Police force was merged into Hertfordshire. Local policing is overseen by the Local Policing Command, headed by a Chief Superintendent. The county is sub-divided in to 10 Community Safety Partnerships, which broadly correspond to the local Borough and Council areas. The 10 CSPs, each headed by a Chief Inspector are: Watford, Three Rivers, Dacorum, Welwyn and Hatfield, St Albans, Hertsmere, East Herts, Broxbourne, Stevenage and North Herts.
