Four people have been arrested on suspicion of criminal damage after custard and apple crumble were thrown at a display case containing the Imperial State Crown at the Tower of London. Take Back Power, which describes itself as a new non-violent civil-resistance group, claimed it was behind the act. This is the second demonstration claimed by the group in the past few days. The Tower's Jewel House was temporarily closed to the public while the police investigated but has now reopened.
