A mass protest against tuition fees by more than 45,000 students turned violent as a huge procession to the House of Commons passed David Cameron's campaign headquarters.
Trouble-makers surged through police lines and occupied the lobby of the Millbank Tower.
About 50 protesters got on to the roof, dropping a large metal fire extinguisher on to riot police. One waved a black and red anarchist flag at the cheering crowd below.
