In a new video, entitled Shred The Love, The Director's Cut, Banksy has revealed that he carried out rehearsals for the headline-grabbing prank, and that in practice runs the secret shredder hidden inside the painting's Victorian-style frame had "worked every time".
His Girl With Balloon was bought for £1.04 million by a European art collector - but nearly as soon as the hammer fell, the canvas was passed through a secret shredder hidden in the large Victorian-style frame, leaving the bottom half in tatters and only a solitary red balloon left on a white background in the frame.
At Sotheby's, however, the spray-paint and acrylic on canvas only went halfway through the shredder.More news: 10m tweets by Russian and Iranian trolls released
Alex Branczik, Sotheby's head of contemporary art in Europe, has also reiterated in a new interview that the auction house was not in on the stunt.

The pic with a snapchat eye-emoji on it shows a man in a white scarf, wearing some kind of a wrist band or watch, hat and black glasses with some device on him allegedly in the same Sotheby's room where the shredding took place.
The glitch makes the new form of "Girl with Balloon" much easier to display on walls, and the art experts say the artwork, now renamed "Love Is in the Bin", is now worth significantly more than the $1.4 million paid by the victor (who has chose to keep the piece).More news: Salmonella in raw chicken makes 92 people sick, CDC says
Girl With Balloon appeared on a wall in Great Eastern Street, London.
The artwork was signed and dedicated and the vendor acquired it from the artist in 2006, the auction house said. Despite claims to the contrary, however, the work actually fell short of Banksy's artist record at auction-set with the sale of Keep it Spotless (2007) for $1,870,000 at Sotheby's NY in February 2008.
The lot had been estimated to sell for £200,000 to £300,000 before the auction.More news: Individual grades from win against Cleveland Cavaliers
