Vincenzo Perugia, an Italian petty criminal who worked at the Louvre, hid in the museum's gallery until closing time and then removed the Mona Lisa from its frame, probably smuggling it out the next day. Perugia was under the impression that the Mona Lisa had been stolen by Napoleon and by returning it to Italy he doing his patriotic duty, and therefore he asked for 500,000 lire as a reward.
Fellow Italian Alfredo Geri agreed to take a look at the painting and Perugia took the painting to Geri’s gallery where he was persuaded to leave it for an expert to examine it - by the end of that day the police had arrested Perugia.
