Even if you are Banksy, tagging is forbidden on London's Underground.
Transport for London, the transportation agency for the greater London area, scrubbed the acclaimed street artist's latest work on the subject of Covid-19 from one of its trains, erasing a visual warning on the dangers of skipping face coverings.
It was captioned "If you don't mask - you don't get".
Sky News reported that cleaners who removed the artwork did not know it was by Banksy.
Transport for London said it only became aware it was a Banksy artwork after he released a video showing how it was painted, by which time it had been removed.
Banksy uploaded a 59-second video to his Instagram and YouTube pages yesterday that showed him spray painting on a Circle Line train.
