Frederic Thut, an auctioneer with Fine Art Auctions in Miami has called on campaigners to prove their claims that the Banksy art work 'Slave Labour' was taken illegally from a wall in Wood Green.
Mr Thut said that the company would not sell the controversial art work if the community could prove it was stolen.
We heard that some people in England are complaining that the work has been stolen. That is completely incorrect because the work was painted on a private wall and the owner of a private wall can do whatever he wants with his own wall. Maybe the public thinks they own something, but in fact the only owner is the owner of the wall.
We have been contacted by some authorities, and we asked them to give us the proof that this work is illegal to sell. As soon as they do that, we will not sell it because we do not have the right to sell illegally. We are a legal company, and we are proving our responsibility as much as we can. We will not sell this work if there is any legal problem with it.
Locals in Harringay have been protesting against the sale of a Banksy which was taken from the wall of Poundland in Wood Green.
It appears graffiti artist Banksy has had the final word after a piece of his artwork was ripped from a wall in a London street.
A Banksy mural, which was removed from a London wall, has appeared for sale at a Miami auction house, with bids starting at $400,000.
