Police box

A police box is a British telephone kiosk or callbox located in a public place for the use of members of the police, or for members of the public to contact the police. Unlike an ordinary callbox, its telephone is located behind a hinged door so it can be used from the outside, and the interior of the box is, in effect, a miniature police station for use by police officers to read and fill out reports, take meal breaks, and even temporarily hold prisoners until the arrival of transport.
