The murder of Ilan Halimi was the kidnapping, torture, and murder of a young Frenchman of Moroccan Jewish ancestry in France in 2006. Halimi was kidnapped on 21 January 2006 by a group calling themselves the Gang of Barbarians. The kidnappers, believing that all Jews are rich, repeatedly contacted the victim's modestly placed family demanding very large sums of money. Halimi was held captive and tortured for three weeks, and died of his injuries. The case drew national and international attention as an example of antisemitism in France.
