Two suspected student fees protesters have been accused of trying to gain entry to Buckingham Palace.
Matthew Bellis, 26, and Laurence Flanders, 20, have been charged with trespassing on a site protected under the Serious Organised Crime and Police Act 2005, during the riots against student fees.
It has also emerged that a protester who allegedly attacked the Royal convoy during the riots is also suspected of throwing a barrier at police and kicking the windows of a shop.
Meanwhile, new footage uploaded to YouTube and seized by officers shows a hooded man throwing a petrol bomb towards police during the December 9 riots. The man is wearing a dark coat and he is carrying a light rucksack with black and red writing on it.
Detective Chief Superintendent Matthew Horne, heading the special fees protest unit known as Operation Malone, said: “What we have released today is the unlawful side of protest. An individual brandishes what appears to be a petrol bomb, putting others in clear danger. Another young man is seen committing acts of suspected violent disorder in Parliament Square, attempting to cause damage to shops and attacking the Royal Convoy.”
Police have released details of wanted suspects and witnesses, including still images and video clips.
More than 200 people have been arrested in connection with violence and damage caused during the protests.
Edward Woollard, 18, was jailed for 32 months earlier this week after admitting throwing a fire extinguisher off the roof of the Conservative Party HQ in Millbank, narrowly avoiding hitting the people below.
