Called 'Piranhas', the work includes spray-painted fish on a police sentry box in the City of London.

Even the death penalty isn't off the table - not just for murder or mutiny, but for damaging an oil or gas pipeline or a sentry caught sleeping on duty.

The City of London Corporation said the other painted on 11 August - swimming piranhas on a City of London Police sentry box - had been taken to Guildhall Yard so it could be viewed safely.

The public then flooded to see the swimming piranhas, which appeared on the side of a City of London Police sentry box.
