Thousands of protesters wearing Guy Fawkes masks clashed with the police in London last night’s protest organized by Anonymous group causing serious damages.

Violence erupted as the crowd of protesters tried to head to Buckingham Palace and Leicester Square. A total of 50 people have been arrested and at least three officers have been taken to hospital with injuries.

Bottles were thrown over the barriers towards officers, while protesters were shouting ‘Shame on you, we’re human too.’ A line of police and mounted officers formed a barrier against the protesters.

Self-proclaimed anarchist Aztecarna Peatonito, from Mexico, said he wanted to fight inequality. ‘We tried for six years to get the Press to take us seriously,’ he said. ‘It is only when we wore the masks that we started getting attention.’, Daily Mail reports.
