Four people have been arrested after activists smothered apple crumble and custard over a glass case containing the Crown Jewels inside the Tower of London, this morning. The campaigners, who have identified themselves as members of Take Back Power, then unfurled a sign saying: 'Democracy has crumbled - tax the rich'. It is the third action carried out in the last five days by the group. #crumble #london #crown #arrest #police
