The season finale sees Christopher’s character ask his supervisor if he should paint over the famous work. But, his probation officer seems to be paying little attention and consequently doesn’t realise it’s an original Banksy.
She tells him all graffiti must be painted over, which he then does.
Banksy’s artwork are often worth millions of pounds and appear casually overnight in unanticipated locations.
The Outlaws is available to stream now on BBC iPlayer.
