Thousands of anti-capitalist activists took to the streets of central London on Bonfire night to protest against "political oppression", with ten people arrested as masked marchers clashed with police. Demonstrators wearing Guy Fawkes masks and carrying banners and placards descended on Trafalgar Square before marching towards Parliament Square at 6.30pm. Protesters chanted anti-establishment slogans as they milled around, and some who had climbed on to the base of Nelson's Column let off fireworks.
There was a heavy police presence at both Trafalgar Square and Parliament Square, as well as along Whitehall, with officers carrying riot gear, but the protest began peacefully. The entire protest was filmed and streamed live online. Footage showed protesters pushing over bins, shouting at bemused shoppers and commuters and hitting cars and people with yellow flexible tubes. In one section they surrounded a man driving a new Mercedes car and sprayed the back of it with an aerosol, pushing their tubes at him as he opened windows to remonstrate with them. There was a chorus of boos and whistles as an officer from the Metropolitan Police warned protesters about their behaviour over a loud hailer. The protest, the so-called Million Masks March, was organised by activist group Anonymous.
