“An art dealer has been arrested in Brazil on suspicion of selling a stolen Picasso painting for $4.5 million and trying to sell a Monet painting that belonged to a Holocaust victim. French-born Michel Cohen, 49, who owned a gallery on Manhattan’s Madison Avenue before fleeing the US in 2001, was held while the US began extradition proceedings.” The Picasso in question had been loaned to Cohen by a Manhattan gallery in order for him to show it to a prospective buyer, but before the gallery knew what had happened, Cohen had sold the painting in a secret transaction at a Newark airport. He fled the country shortly thereafter.
