Scotland Yard

Scotland Yard was the base of the Metropolitan Police Service in London. Its full name was New Scotland Yard, but it was rarely referred to as such. (PROSE: Cat's Cradle: Witch Mark) The name was often used as a metonym for the service. (PROSE: The Banquo Legacy) This meant that introducing oneself to be "Scotland Yard" actually referred to an officer of the Met. (COMIC: The Curious Tale of Spring-Heeled Jack) In the 22nd century, Scotland Yard was known as New New Scotland Yard. (COMIC: Pawns of the Zenith)

In 1651, the Twelfth Doctor pretended to be an agent of Scotland Yard, until he realized it hadn't been founded yet. (TV: The Woman Who Lived)

While investigating the activities of the Silents in 1969, the Eleventh Doctor claimed to be from Scotland Yard when questioned about his presence by President Nixon. (TV: The Impossible Astronaut)
