An inquiry is under way after a person broke into the Tower of London and stole a set of keys.

The incident took place in the early hours of 6 November and the intruder got past the first gate, a spokeswoman for the Historic Royal Palaces said.

Keys for a restaurant, conference rooms and an internal lock to the drawbridges were on the stolen set. The locks have now been changed.

Robert Hall reports.
