Four people went to the Tower of London. They threw custard and apple crumble at the glass case with the Imperial State Crown inside. The police came and arrested the four people. The police said they did this because they wanted the government to listen to the people.

The group called Take Back Power said they did this. They want the government to make a new group of people to help make big decisions. Some people in the government said this action was not good. The Tower of London closed for a short time, but it opened again later. The crown was not broken or hurt.

The Imperial State Crown is very important in the United Kingdom. The King wears this crown at special events. When the King does not use it, people can see it at the Tower of London. The crown has many diamonds and other stones. It is very old and very special.
