A source at Sotheby’s, who spoke on the condition of anonymity, said that the Banksy camp had insisted on securing an unusually high number of seats for the sale. Some onlookers reported seeing one of these people with a device in his hand after the shredding happened, and that he was detained by security as he tried to leave.
“We have not experienced a work spontaneously shredding after it sells for a million pounds,” Sotheby’s Europe head of Contemporary Art, Alex Branczik said at the press conference.
He absolutely denied any knowledge that such an act was coming.
“We got Banksy’d,” he said.
