# European museum theft trends and incidents > Live situation record from CLSTR: https://clstr.news/situations/european-museum-theft-trends-and-incidents > Updated: 2026-08-27T19:51:34.000Z. Sources: 100. Developments: 2. Europol has reported a significant shift in European museum thefts, noting that crimes are becoming increasingly violent and aggressive. While traditionally characterized by stealth, modern heists now frequently utilize tools such as sledgehammers, axes, crowbars, and explosives, with some instances involving firearms to intimidate security and visitors. The focus of these thefts has moved from high-profile artworks toward precious metals, gemstones, and culturally significant artifacts. This trend is attributed to the rising value of gold and the ease with which such items can be liquidated on the illegal market. Additionally, the criminal landscape is evolving from specialized, hierarchical gangs toward decentralized, ad-hoc groups recruited through social media under a ‘crime-as-a-service’ model. Recent incidents illustrate these trends, including a robbery at the Archaeological Museum of Villena in Spain, where thieves stole a Bronze Age gold treasure. A major theft also occurred at the Museum of Applied Arts (MAK) in Vienna during its ‘Glanzstücke’ exhibition. Two unidentified men, described as wearing black clothing, entered the museum as regular visitors before smashing a glass display case to steal a historic Van Cleef & Arpels diamond necklace. The necklace, which features 673 diamonds exceeding 200 carats, was originally worn by Queen Nazli of Egypt in 1939. It previously sold at a New York auction in 2015 for approximately $4.3 million. Austrian police are currently conducting an intensive manhunt, analyzing surveillance footage of the suspects to track the perpetrators. Police have released descriptions of the suspects as two men of slim build, approximately 170 to 175 cm tall, with dark hair and beards, wearing black clothing and dark athletic shoes. While the museum has temporarily closed the affected exhibition, the institution remains open to the public. ## Claims - A valuable diamond necklace was stolen from a museum in Vienna, according to Austrian police.
