A new artwork by Banksy that shows a judge hitting a protester with his gavel has appeared on the front of the Royal Courts of Justice in London - only to be swiftly covered up by officials.
Security guards were seen patrolling in front of a screen concealing the mural now confirmed as being by the guerilla graffiti artist as his latest creation.
He shared an image of it on his Instagram page, after it was stencilled on an external wall of the Queen's Building but swiftly hidden by large sheets of black plastic and two metal barriers.
The artwork follows almost 900 people being arrested in central London at Saturday's demonstration supporting banned group Palestine Action, in what is thought to be Britain's biggest ever mass arrest.
Scotland Yard condemned what police called the 'intolerable' abuse of its officers suffered during the rally in Parliament Square, in Westminster, attended by an estimated 1,500 people.
