The Tower of London has been forced to close after an incident involving the display case housing the Crown Jewels.
Four people have been arrested on suspicion of causing criminal damage after food was allegedly thrown at the protective cases containing the historic items.
The popular tourist attraction in central London was shut to the public to allow officers to secure the scene and carry out forensic and investigative work.

“It was reported that four protesters threw suspected food onto the case before two left the scene.
