Royal Botanic Gardens Constabulary arm patch

Royal Botanic Gardens Constabulary is a very small, specialised constabulary responsible for policing the Royal Botanic Gardens at Kew in Richmond-upon-Thames, England. The Royal Botanic Gardens Constabulary was established in 1845.
The amended Parks Regulations 1872 gives Kew Constabulary police powers within all the parks to which the legislation applies. Whilst there is nothing to suggest that Kew Constabulary Police Officers would ever find themselves exercising their police powers in another park, this legislative quirk remains nonetheless.
