Police hunting those responsible for violence and criminal damage during student protests have released images of a man throwing a petrol bomb.
The hooded figure can be seen running across Parliament Square and throwing a flaming bottle across a crowd of protesters in footage recorded by a member of the public during one of the most violent days of demonstrations on December 9.
Investigators have also obtained images of a second suspect attacking cars in a royal convoy in Regent Street on the same day.
He was also caught on camera kicking in the windows of a branch of Topshop in Oxford Circus and throwing a metal fence at police officers.
A further 10 still images have been released of people suspected of violence and other offences on November 24.
Senior officers at the Met have formed a specialist unit, dubbed Operation Malone, to bring those who broke the law to justice. They have arrested more than 200 suspects, the majority in their late teens and early twenties, since the first protest on November 10.
The release of the images comes as two suspected anti-Government protesters were charged with trespassing at Buckingham Palace.
Matthew Bellis, 26, and Laurence Flanders, 20, were arrested by Metropolitan Police officers on Wednesday morning as they apparently tried to talk their way inside at the staff entrance to the palace, on Buckingham Palace Road.
A Metropolitan Police spokesman said the pair appeared at City of Westminster Magistrates' Court on Thursday afternoon charged with trespassing on a site protected under the Serious Organised Crime and Police Act 2005 and were remanded in custody until next Thursday.
It is understood Bellis, of Brendon Close, Harlington, west London, and Flanders, of Ridgemont Road, Stroud, Gloucestershire, were carrying political banners criticising Government cuts and accusing politicians of lying.
