If you find some police officers in your ancestry and they served in the Metropolitan Police Force then this is the site for you.

Timelines, gallery of old images, history of policing and details of the archives. Plenty to read and see and there is advice on how to access and use the records that the archives hold.

Plus there are pages dedicated to some of the more famous historical criminals that the Met has had dealings with.
