Eight men were jailed over a double heist on the Harry Winston store in Paris that netted watches and jewels worth more than $100 million. Nicknamed the Pink Panthers (after the well-known TV series) by Interpol, this international jewel thief network was composed mainly of ethnic Serbs and Montenegrins. How did they accomplish such a feat you ask? Four men pretended to be builders in the first heist in October 2007. A year later, four thieves gained access again, three of them wearing women’s clothes and wigs. In March 2011, police found $19 million in jewelry from the 2008 heist stuffed in a drain in a home in the Parisian suburb of Seine-Saint-Denis, but much of the loot has not been recovered.
