The Catalonia regional police force, Mossos d’Esquadra, said on Thursday it had raided a workshop inside an apartment in the city of Zaragoza, where the forgers were producing their forged products before distributing them through auction rooms, antique shops, or online platforms.

Investigators have seized nine works and recorded at least 25 sales to victims in Spain, Germany, Switzerland, the United States, and Scotland, the Mossos added in a statement. Four people are under investigation, charged with fraud and crimes against intellectual property.

How forgers operated

According to the police, “a couple of young followers of Banksy’s street art with economic problems” created Banksy-style works with stencils and ink stamps from the Zaragoza workshop, which they at first sold at prices no higher than EUR 80.

However, a distributor “with knowledge of the functioning of the graphic work market,” in collaboration with an “interested distribution entity,” made fake certificates attributing the works to the secretive Banksy, whose identity has never been revealed.

The artworks were presented as being part of Banksy’s “Dismaland” project, a 2015 theme park-style installation in the British town of Weston-super-Mare.

One detail missing

But the company Pest Control, the only body that certifies Banksy’s oeuvre, found that both the artworks and certificates were false.

“The investigation remains open, and further victims and new arrests are not ruled out,” the Mossos concluded.
