British police are investigating how an intruder breached the walls of the Tower of London and stole a set of keys from the tourist attraction and home of the crown jewels. Locks to the Tower's drawbridges and other rooms have been changed after a man was caught trespassing in the early hours of November 6 and escorted from the premises, according to a royal palaces statement.
