Three gunmen in ski masks and dark clothes burst into a museum in Zurich just before closing time. After a quick run through the building, they hustled out the door and sped off with paintings by Cezanne, Degas, van Gogh and Monet valued at $163.2 million.

Authorities appealed Feb. 11 for any witnesses to help reconstruct the robbers' getaway from the E.G. Buehrle Collection, a private museum of Impressionist works.

"This is an entirely new dimension in criminal culture," police spokesman Marco Cortesi said, calling it the largest art robbery in Switzerland's history and one of the biggest ever in Europe.
