Video footage was released today (28 May) of clashes between protesters and police in London at an anti-austerity march after the State Opening of Parliament yesterday.

In the images filmed by Reuters, demonstrators clad in balaclavas and Guy Fawkes masks, synonymous with the Anonymous protest group, grapple and shove with police officers. Scotland Yard said three people – including a 17-year-old – had been arrested on suspicion of assault.

A man, whose age has not been given, was arrested on suspicion of violent disorder and possession of an offensive weapon. A 45-year-old man was also arrested on suspicion of violent disorder in relation to an incident in Whitehall on 9 May.

Waving placards and flags, the 200-strong protest began in Trafalgar Square, before making its way along Whitehall towards Downing Street. As skirmishes broke out between both sides, police pulled out their batons and linked arms to form a barricade.

The activists, who came from three separate groups, Youth Fight Against Jobs, The National Campaign Against Fees and Cuts and The People's Assembly, were protesting against the continued austerity measures due to be implemented by the new all-Tory government.
