Paintings by famous modern artists disappeared from an exhibition in the Netherlands in a predawn art heist Tuesday, shutting down an exhibition in the Kunsthal Rotterdam, where works by Pablo Picasso, Vincent van Gogh, Andy Warhol and Claude Monet are on display.
Paintings of "considerable value" disappeared in the museum theft, spokeswoman Mariette Maaskant said on Netherlands public radio.
The works belong to a private collection that is being shown for the first time to the public, according to a Kunsthal statement.
The Triton Collection has taken 20 years to assemble and includes more than 150 works of modern art from the "late nineteenth century to the present day." It spans art movements from impressionism and expressionism to cubism and constructivism.
Its roster of artists boasts the names of Marcel Duchamp, Piet Mondriaan and George Braque, to name just a few.
Police plan to release the names of the artwork stolen and information about the break-in and suspects later Tuesday, Ekkers said.
