Help yourself to a sizeable pinch of salt before watching this clip, shot in Melbourne, that purports to show secretive graffiti artist Banksy at work.
The video was uploaded to Youtube by a woman called Mia, who wrote: "So I was walking home from work late last night and I was watching a street artist doing a piece in Hosier Lane.
"I double backed and pulled out my phone as he was finishing up. Can't believe I just met Banksy !"
The video shows a hooded figure finishing off a mural in an alley, before the camerawoman pursues him.
The mural was a stencilled (Banksy-ish) image of Pauline Hanson leader of Australia's right wing One Nation party, wearing a t-shirt saying "F*** off - W're fools."
