15. The Rotterdam Art Heist
Date: October 16, 2012
Rotterdam's Kunsthal Gallery was robbed of seven masterpieces painted by Picasso, Monet, Gauguin, Matisse, and Lucian Freud. The event, which occurred days after the vandalism of a Rothko painting at the Tate Modern in London, was yet another reminder of the fragile security at museums. At this point, the thieves have not been caught.
