European police have busted a criminal ring that over a period of two years stole rare books by famous Russian authors from libraries across Europe. Europol says it has arrested four Georgian nationals in Georgia and Lithuania who are thought to have collaborated in the plot, in which at least 170 books were stolen by Russian writers including Pushkin and Nikolai Gogol.
