7. Gurlitt: The $100m Nazi Hoard
A collection of modern masterpieces was seized by police in 2012, in a run down Munich apartment, after a routine stop and search on a train revealed that Cornelius Gurlitt, the son of a prominent Nazi art dealer, was carrying nearly 10,000 euros in cash. Tax authorities later searched his residence uncovering a hoard of 1,400 works of art including, Picasso, Matisse, Monet, Renoir and Franz Marc. The works of art are thought to be worth up to $100 million. A further 60 works were also discovered in his house near Salzburg. Many have now been restituted to their rightful owners
