European museum robberies have become more violent, with traditional specialist gangs giving way to loosely organised groups of opportunists hired through social media, according to a new report from Europol, the European Union’s law enforcement agency, published on August 24.
The agency’s spotlight analysis, titled Changing tactics, changing targets: the evolving nature of museum heists, documents a clear shift away from the classic image of discreet, non-violent cultural property crime towards confrontational attacks that rely on force and intimidation.
Offenders are increasingly using sledgehammers, axes, crowbars, firearms and, in some cases, explosives to smash their way into premises and display cases.
Staff and visitors have been threatened or assaulted, with the report citing cases in which employees were tied up or overpowered by brute force.
Europol notes that many of those involved are not long-standing art thieves but individuals with backgrounds in other forms of crime who are assembled on an ad-hoc, “crime-as-a-service” basis via social media and instant messaging. The agency says such recruits frequently have no prior connection to each other.
This decentralised model replaces the tighter hierarchical networks that once dominated the illicit trade in cultural goods, which typically formed a core group around a single leader.
The choice of targets has also changed. Thieves are concentrating on precious metals, gemstones and culturally significant artefacts that can be melted down, broken up or quickly resold with less risk of identification.
Gold prices have risen sharply in recent years, adding to the attraction. The metal set 53 record highs during 2025 and returned 67 per cent over the year, according to the World Gold Council.
A second trend concerns Chinese cultural objects. Europol lists porcelain plates from the 12th and 13th centuries, Ming dynasty jars and enamelled bronze vases among the pieces taken, including items stolen from the Keramiekmuseum Princessehof in Leeuwarden, northern Netherlands.
High-profile examples cited in the report include the October 19, 2025 Louvre heist in Paris, in which thieves broke a window and threatened guards and visitors in broad daylight before smashing display cases in the Apollo Gallery and stealing jewellery valued at around €88 million, including Empress Eugénie’s tiara. Several people have been placed under formal investigation and the eight stolen pieces have not been recovered.
The report also details a raid on the night of January 24-25, 2025 at the Drents Museum in Assen, northeast Netherlands, in which explosives were detonated at a door to steal a 2,500-year-old Dacian golden helmet and three ancient gold bracelets. The helmet and two of the bracelets were handed back on April 1, 2026 after an agreement between prosecutors and the suspects, and returned to Romania; the third bracelet is still missing.
A 2024 attack on the Cognacq-Jay museum in Paris is also cited, in which four hooded suspects carrying baseball bats and axes seized seven gold and diamond-set objects before escaping on scooters.
Europol’s European Serious and Organised Crime Centre (ESOCC) has supported several of the national investigations linked to these cases. In November 2025 it coordinated an operation across several member states that dismantled a network trafficking antique gold and silver coins and other antiquities, with 35 arrests in Bulgaria.
The agency warns that the combination of greater violence, easier recruitment and the ready convertibility of gold and jewels into untraceable cash is raising the threat level for museums across Europe and complicating efforts to protect cultural heritage.
