It seems art thieves are becoming more active these days. Not long ago thieves stole 2 Picasso paintings. Now 4 more paintings have been stolen from a EG Buehrle Collection in Zurich. Masked thieves broke in and stole masterpieces by Cézanne, Degas, Van Gogh and Monet worth $170 million. The stolen masterpieces are "Poppies near Vétheuil" by Claude Monet, "Count Lepic and his Daughters" by Edgar Degas, "Blossoming Chestnut Branch" by Vincent Van Gogh and "Boy in a Red Waistcoat" by Paul Cézanne. This is the biggest art robbery in Europe since 1988 when three Van Gogh works worth £94 million

5 Drunk people broke into the Orsay Museum through a back door early Sunday and punched a hole in a renowned work by Impressionist painter Claude Monet. A camera caught a group of five people entering the museum. "We know there were four or five people, likely four boys and a girl, who entered around midnight to 1 a.m., broke a door that was, perhaps, fragile," Albanel said. "It appears they were drunk. Someone punched the magnificent masterpiece by Monet."CNN
