Europol has warned that museum thefts across Europe are becoming increasingly aggressive, with offenders using forceful methods and focusing on high-value items such as precious metals, gemstones and culturally significant artefacts. The findings are contained in a new spotlight report titled “Changing tactics, changing targets: the evolving nature of museum heists,” which examines shifts in the methods, targets and criminal profiles associated with cultural property theft.
The report points to a move away from some of the more traditional forms of cultural property crime towards attacks involving greater levels of violence and physical force. It also highlights the involvement of criminal actors from outside the conventional cultural property trafficking environment, including opportunistic groups attracted by the potential profits from museum theft.
Europol said the changing pattern requires closer attention from law enforcement agencies as museums and cultural institutions face increasingly organised and aggressive attempts to steal valuable objects.

Sledgehammers, Explosives and Firearms Used in Museum Attacks
One of the key findings is the growing use of violent methods during museum thefts. Europol said offenders are increasingly using tools such as sledgehammers, explosives and firearms to gain access to premises and intimidate staff.
The use of such methods marks a significant shift in the nature of museum crime, where offenders may be prepared to damage buildings, displays and security systems to reach valuable objects.
The report also found that thieves are increasingly targeting items with strong resale potential. Precious metals, gemstones and culturally significant artefacts are among the objects attracting particular attention.
Europol linked this trend to high market demand and the relative ease with which some stolen items may be moved or resold through illicit channels.
New Criminal Groups Enter the Cultural Property Market
The report also identifies changes in the profile of those involved in museum thefts.
Europol said some offences are being carried out by new or ad-hoc groups, including individuals recruited through social media. This represents a departure from the more traditional networks associated with non-violent cultural property trafficking.
The agency also identified what it described as cross-market opportunities, with offenders involved in other criminal sectors apparently becoming attracted to museum theft because of its perceived low-risk and high-profit potential.
The findings suggest that cultural property crime is increasingly overlapping with other forms of organised criminal activity. This could make investigations more complex, particularly where groups move between different illicit markets and use existing criminal networks to sell or transport stolen items.
The involvement of opportunistic offenders also means that law enforcement agencies may need to look beyond established art and antiquities trafficking networks when investigating museum thefts.
Louvre and Dacian Artefact Cases Highlight Changing Threat
Europol cited several prominent cases to illustrate the changing nature of museum crime.
These included the theft of Dacian artefacts in the Netherlands in 2025, the Louvre heist in France in 2025 and the attack on the Cognacq-Jay Museum in France in 2024.
The investigations into these cases have received support from property crime specialists working through Europol’s European Serious and Organised Crime Centre.
Europol said its role includes providing operational, analytical and coordination support to investigators in European Union member states dealing with cultural property offences.
The agency said such cooperation is an important part of efforts to combat the illegal trade in cultural goods, particularly as offenders adopt more aggressive tactics and expand their targets.
The latest report indicates that museum security threats are no longer limited to conventional theft by specialised art criminals. Instead, law enforcement agencies are confronting a broader mix of violent offenders, opportunistic groups and criminal networks targeting valuable cultural property for financial gain.
