Royal Parks Operational Command Unit
Core police teams provide 24-hour coverage to the 17 Royal Parks, Gardens and other open spaces within the Metropolitan Police District - an area in excess of 6,000 acres (24 km2).
Spread across the five boroughs in which the various Parks are located, the pan-London service given by the Royal Parks Operational Command Unit is in addition to that provided by local borough police. The unit is currently commanded by a Superintendent.
The OCU began to take over policing responsibility for the parks in April 2004 during a period of transfer of functions from the Royal Parks Constabulary (RPC). The RPC was finally abolished as a constabulary in 2006.
The OCU is responsible for policing Abingdon Street Garden; the Barge Walk Hampton Court; Brompton Cemetery; Bushy Park; the Longford River, and those parts of its banks which are for the time being under the control of the DCMS; Greenwich Park; Grosvenor Square Gardens; Hyde Park; Kensington Gardens; Primrose Hill; Regent's Park; Richmond Park; St. James's Park; Green Park; Victoria Tower Gardens.
