The new mural on London’s High Court is thought to criticise Britain’s crackdown on protests in solidarity with Palestine Action group.

Anonymous street artist Banksy has unveiled a new mural on London’s High Court, depicting a judge striking a protester with a gavel, in what appears to be a commentary on the mass arrests of demonstrators backing the banned campaign group Palestine Action.

The anonymous artist shared images of the work on Instagram on Monday. The stencilled piece shows a bewigged judge bringing down a gavel on a protester sprawled on the ground, clutching a blood-stained placard.

The mural was painted days after nearly 900 people were detained during a protest in London opposing the government’s proscription of Palestine Action.

The artwork has since been fully covered up by British police, after attracting curious bystanders.
