Banksy could finally be unmasked as police investigate latest artwork

The artwork depicts a judge attacking a protester

Metropolitan Police officers immediately covered up the artwork, and the force has since launched an investigation.

The graffiti, which appeared on an external wall of the Queen's Building, is being investigated as potential "criminal damage".

The artwork has since been concealed by large sheets of black plastic and two metal barriers.

Less than 24 hours after its appearance on the Grade I-listed building, HM Courts and Tribunals (HMCTS) established that it would be removed.

A spokesperson for HMCTS added: "The Royal Courts of Justice is a listed building and HMCTS is obliged to maintain its original character."

Even though Banksy has not yet claimed the piece, Defend Our Juries suggested it was the artist's doing.

The artwork comes two days after 890 demonstrators were arrested during a rally in central London following the banning of Palestine Action as a terror organisation.

"We hope everyone who is moved by Banksy’s inspiring work of art will join our next action, which will be announced soon."

Criminal damage, what Banksy's work is deemed as, carries a maximum sentence of 10 years' imprisonment if the damage racks up a cost of over £5,000.

Offences where the damage is worth less than £5,000, a maximum sentence of three months or a £2,500 fine would apply.
