Four protesters from "Take Back Power" disrupted the "Imperial State Crown" display at the "Tower of London", forcing a temporary closure of the "Jewel House" as police opened an investigation, conducted security checks and cleaned the area.Among them was Zahra Ali, 19, who joined others demanding social reforms including a permanent citizens’ assembly with taxing powers over the wealthy, redistribution to tackle child hunger and measures they said would counter a rise in fascism.Observers compared the action to "Just Stop Oil" attacks on artworks, video shows two protesters attacking the case while others smeared apple crumble and poured yellow custard and unfurled a sign reading “Democracy has crumbled. Tax the rich”, and officials said no damage was found to the "Crown Jewels" and four people were arrested.
