It is not unusual that artefacts, valuable treasures in a cultural heritage fall victim of unlawful deeds, they are stolen, smuggled out of the country or even abducted. It can happen in national museums, village museums even private collections, too. According to date provided by KÖH, stealing works of art may occur 700-800 times in Hungary on a yearly basis, with damage accounting to one-billion HFt. Statistics reveal that the number of cases lessens; on the other hand, the value of loss grows due to the ever increasing professionalism of the perpetrators.
