At the Tower of London, activists threw a pie at a display with the crown of the British Empire.

The display case with the crown of the British Empire in the Tower of London was attacked with apple pie and custard, reports the BBC. A new civil resistance movement, Take Back Power, claimed responsibility for the incident.

Activists threw a pie into the window and poured custard on it. One shouted: “Democracy has collapsed,” while another added: “Britain is broken. We have come here to the nation’s treasure to take back power.”

The Take Back Power movement published a demand on social networks for the government to create a permanent citizens’ assembly, which they called the “House of the People.” This House should be empowered to “tax super-wealth and fix Britain”.

Police said four people were detained on charges of intentionally causing damage. The display with the Crown of the British Empire is temporarily closed.
