West Yorkshire Metropolitan Police was formed in 1974, when part of the
West Yorkshire Constabulary (itself created in 1968, and covering a much larger area) was amalgamated with the
Leeds City Police and
Bradford City Police, under the
Local Government Act 1972. The force was originally known as the
West Yorkshire Constabulary . Some older signs around the Force area, such as the one in the reception of Millgarth Police Station in Leeds city centre, read 'West Yorkshire Metropolitan Police'. The 'Metropolitan' from the police title was dropped in 1986 when the
metropolitan county councils were abolished. The new Force was known as the present West Yorkshire Police. Proposals made by the
Home Secretary on 21 March 2006 would see the force merge with
North Yorkshire Police,
South Yorkshire Police and
Humberside Police to form a strategic police force for the entire region. This did not take place. On 12 December 2006,
Sir Norman Bettison was announced as the new chief constable, replacing
Colin Cramphorn and resigned from his post on 24 October 2012. He was replaced by Temporary Chief Constable John Parkinson until the appointment of Mark Gilmore as chief constable on 1 February 2013. In 2018, it was reckoned West Yorkshire Police would lose 400 officers from its 4,800 officers due to
austerity. In August 2023, the West Yorkshire Police attracted controversy when they arrested an autistic 16-year-old girl in Leeds for telling a female police officer that she looked like her 'lesbian nana' while in her own home. ==Operational structure==
