British street artist Banksy painted a new mural on London's High Court depicting a judge beating a protester.

The artist, whose identity has never been confirmed, published pictures of the artwork on his Instagram page on Monday, Sept. 8, according to Reuters.

The black, white and red mural shows a wigged judge using a gavel to hit a protester holding a blood-splattered placard who has been knocked to the ground.

The artwork comes after protests against the ban of Palestine Action on Saturday, Sept. 6, that resulted in the arrest of nearly 900 people, according to the BBC.

Britain labeled Palestine Action as a terrorist organisation in July, making it a crime to belong to or support the group, after some of its members broke into a Royal Air Force base and damaged military planes.

Although the Bristol-based artist never comments on his artwork, he has created previous work in support of Palestinian causes, including murals on the West Bank separation barrier, concentrated around Bethlehem.

Labor Party politician and UK Special Envoy for Women and Girls Baroness Harriet Harman told the BBC that the mural was a "protest about the law."

"Parliament makes the law, and the judges simply interpret the law," Harman said. "I don't think there's any evidence, in terms of the right to protest, that judges have been clamping down on protests beyond what Parliament intended."

Banksy's London mural covered

The BBC reported that shortly after its reveal, the mural was covered by large sheets of plastic and metal barriers.

Court officials told the outlet that it was "obliged" to maintain the original character of the listed historic building and that it would be removed.

Photos show security guards protecting the walled-off murals. The BBC quoted an unnamed guard as saying that they did not know how long they would remain, but "at least it's not raining."

Reuters contributed to the reporting of this story.
