Having given up on digging his way out with a spoon or launching himself with a giant catapult, Jean-Pierre Treiber, one of France's highest-profile prisoners, escaped by packing himself in a cardboard box. The box was loaded with many others on a truck for a 100 mile journey to to the Yonne region, southeast of Paris. Somewhere during the ride Treiber broke out of the box an made his escape. "We're searching the places where he used to hunt," said a policeman. "But he might well have fled further afield."
