Picasso, Matisse and Monet paintings stolen from Dutch museum
Neither the police nor the museum were immediately able to put a value on the haul, but the theft is one of the art world's most dramatic in recent years and will likely be worth millions.

Picasso, a and Monet paintings stolen from Dutch museum.

I choose that article because it tries to explain the robbery in a museum. Dutch police said on Tuesday that painting of famous artist have been stolen from the Kunsthal museum overnight, in Rotterdam.
Seven painting was be stolen. Differents works by Paul gauguin, Meyer de Haan, or Matisse were in the paintings missing.
The prize of that paintings is unknown. The police and the people that work in the museum has been incapable of put a value on this artistic treasure.
In the artistic and audiovisual aids this theft is one of the most dramatics in years
