Essex Police is a territorial police force responsible for policing the county of Essex in the east of England.

It is one of the largest non-metropolitan police forces in the United Kingdom, employing approximately 3,600 police officers and operating across an area of over 1,400 square miles (3,600 km²) and with a population of around 1.6 million people.

The Chief Constable is Jim Barker-McCardle since September 2009.

Assistant Chief Constable for Media Relations Gary Beautridge is also simultaneously ACC for Area Operations for Kent Police due to the two forces forming a joint Serious Crime Directorate.

Essex Constabulary was formed in 1840. In 1965, the force had an establishment of 1,862 officers.

In 1969 it amalgamated with Southend-on-Sea Borough Police to form Essex and Southend-on-Sea Joint Constabulary, which was renamed as Essex Police in 1974.

Essex Police is one of the United Kingdom's largest non-metropolitan police forces with a strength of approximately 3,600 police officers.

Its headquarters, the Force Information Room (where emergency calls are routed to) and Essex Police College, are all located in Chelmsford, within the Central Division.

Essex ( /ˈɛsɨks/) is a ceremonial and non-metropolitan county in the East of England, and one of the home counties. It is located to the northeast of Greater London. It borders with Cambridgeshire and Suffolk to the north, Hertfordshire to the west, Kent to the South and London to the south west. Essex County Council is the principal local authority for much of the county, sharing functions with twelve district councils. The county town is Chelmsford. The southern Essex boroughs of Thurrock and Southend-on-Sea are governed separately as unitary authorities. It was established in antiquity and formed the eastern portion of the Kingdom of Essex. Sections of the county closer to London are part of the Metropolitan Green Belt, which prohibits development. It is the location of the regionally significant Lakeside Shopping Centre and London Stansted Airport; and the new towns of Basildon and Harlow.

The name Essex originates in the Anglo-Saxon period of the Early Middle Ages and has its root in the Old English Ēastseaxe (i.e. the "East Saxons"), the eastern kingdom of the Saxons. Originally (in 527 AD) it occupied territory to the north of the River Thames, incorporating all of what later became Middlesex and most of what later became Hertfordshire, though its territory was later restricted to lands east of the River Lea.Colchester in the north east of the county is Britain's oldest recorded town, dating back to before the Roman conquest, when it was known as Camulodunum and was sufficiently well-developed to have its own mint. Subsequently the Kingdom of Essex was subsumed into the Kingdom of England and Essex eventually became a county.

Roy Maurice Keane (born 10 August 1971) is an Irish former footballer and manager. In his 18-year playing career, he played for Cobh Ramblers, Nottingham Forest, and Manchester United, before ending his career at Celtic. Keane was a dominating central-midfielder, noted for his aggressive and highly competitive style of play, an attitude which helped him excel as captain of Manchester United from 1997 until his departure in 2005, having joined the club in 1993. Keane helped United achieve a sustained period of success in more than 12 years at the club. He then signed for Celtic but retired as a player less than a year later.

He played at international level for much of his career, representing the Republic of Ireland over a period of 14 years, most of which he spent as captain. He played in every Republic of Ireland game at the 1994 FIFA World Cup, although he was sent home from the 2002 World Cup after an incident with national coach Mick McCarthy.

He was appointed manager of Sunderland shortly after his retirement as a player, and took the club from 23rd position in the Football League Championship in late August to win the division title and gain promotion to the Premier League. Keane's arrival was cited as the catalyst for Sunderland's recovery. He managed to keep Sunderland from relegation in the 2007–08 season, but in his second season as a top-flight manager he left his position with Sunderland in the relegation zone. In April 2009, he was appointed as manager of Ipswich Town, but was sacked by the club in January 2011 with them 19th in the Championship.
