French authorities have opened an investigation into a family kidnapping in western France, the latest in a growing number of violent incidents linked to cryptocurrency holdings.
According to a local report, the case, under review by prosecutors in Rennes, involves five members of the same family who were restrained inside their home on April 20 during a targeted attack believed to be connected to digital assets.
Family held captive in targeted attack
The incident occurred in Ploudalmézeau, where several individuals forced entry into a residence early in the morning. Inside were grandparents, their daughter, and two children, all of whom were tied up.
The children’s father, who works in the cryptocurrency sector, was not present at the time of the break-in. Investigators believe the attackers specifically targeted the household due to that connection. Before leaving, the group reportedly accessed and stole a digital wallet. The extent of financial losses is still being assessed by authorities.
Earlier “wrench attacks” signal escalating pattern
The case follows a series of similar incidents across France. In Verneuil-sur-Seine, a crypto investor and his family were attacked in a home invasion in January, one of three such cases reported within a single week.
Armed assailants reportedly tied up the family and attempted to extract access to digital assets before fleeing. In another case near Cholet, a software architect was abducted, assaulted, and forced to hand over crypto holdings. Investigators say these attacks fit a broader pattern of so-called “wrench attacks,” where physical coercion replaces technical hacking to gain access to funds.
Government signals new security measures
French officials have acknowledged the growing threat. Speaking at Paris Blockchain Week, Jean-Didier Berger said new measures are being developed to counter crypto-linked attacks.
Berger noted that authorities have already launched a prevention tool that has attracted thousands of registrations from concerned users. He added that work is underway with Interior Minister Laurent Nuñez to expand protections. The approach is expected to shift from general warnings to more direct personal security measures aimed at reducing the risk of targeted assaults.
Investigation escalates to specialized unit
Given the nature of the crime, the latest case has been transferred to a specialized interregional jurisdiction in Rennes, which handles complex and organized criminal activity.
Prosecutors have opened multiple lines of inquiry, including organized robbery, kidnapping, unlawful detention, and money laundering carried out by a coordinated group. As of now, no arrests have been reported.
Pattern of crypto-linked violence emerges
The incident adds to a broader trend flagged by French law enforcement. According to national judicial police officials, more than 40 kidnapping or abduction cases tied to cryptocurrency have been recorded in France since the start of the year. These cases often involve attempts to extract private keys or access to digital wallets through coercion, rather than technical exploitation.
The rise in such incidents reflects a shift in criminal tactics. Instead of targeting vulnerabilities in code, attackers are increasingly focusing on individuals believed to control significant digital assets. Unlike traditional bank accounts, cryptocurrency holdings can sometimes be transferred quickly under duress, making individuals direct targets.
Ongoing probe highlights security concerns
Authorities have not disclosed further operational details as the investigation continues. The case highlights the challenges law enforcement faces in addressing crimes that combine digital finance with physical coercion.
As cryptocurrency adoption grows, the intersection between online assets and real-world security risks is drawing increased attention from regulators and police agencies.
