Three men posing as police officers forced their way into a home west of Paris and did not leave until €900,000 in Bitcoin had been transferred to a wallet they controlled, the latest in a pattern of violent attacks targeting cryptocurrency holders in France that produced 19 such incidents in 2025 alone.
What Happened
The attackers gained entry to the couple’s home in Le Chesnay-Rocquencourt, a suburb in the Versailles area, by presenting themselves as police officers. Once inside, one suspect produced a knife and threatened to stab the woman unless her partner transferred his Bitcoin holdings immediately. The threat was direct and the mechanism specific: this was not a robbery of physical assets or cash. The attackers knew their target held Bitcoin and came prepared to demand an on-chain transfer.
After the transfer was confirmed on the blockchain, the attackers tied the man to a sofa, left the couple restrained, and fled in a white van. The woman eventually freed herself, then freed her husband, before alerting a neighbor at approximately 9:00 a.m. local time. No arrests have been made as of March 10.
The Versailles Public Prosecutor’s Office is pursuing charges of kidnapping, armed robbery by an organized gang, and criminal conspiracy. France’s Brigade for the Repression of Banditry, an elite organized crime unit, is handling the investigation.
The Pattern Behind the Incident
This attack does not exist in isolation. France recorded 19 violent crypto-targeted robberies in 2025, the highest figure in Europe. The victims have not been exclusively wealthy or publicly known figures. Previous high-profile cases include the abduction of Ledger co-founder David Balland and the kidnapping of the father of a crypto millionaire in May 2025. The Balland case attracted international attention partly because it involved the severing of a finger sent as proof of captivity.
The common thread across these incidents is the same as the Le Chesnay-Rocquencourt attack: the perpetrators had prior knowledge that their targets held significant cryptocurrency. That intelligence does not come from nowhere. It comes from public social media profiles, leaked data, industry event attendance lists, or social circles where wealth is discussed openly. The attack planning requires knowing who holds crypto before selecting a target.
Why Crypto Creates a Specific Physical Security Problem
Traditional wealth stored in banks is protected by institutional intermediaries. A robber who forces a bank customer to transfer funds faces the bank’s fraud detection systems, reversal mechanisms, and the time delays built into wire transfer infrastructure. None of those protections exist for Bitcoin. A transfer confirmed on-chain is final. The €900,000 moved in Le Chesnay-Rocquencourt cannot be reversed by any authority, frozen by any court order issued after the fact, or recalled through any mechanism the victims or investigators control.
That irreversibility is what makes crypto holders uniquely vulnerable to exactly this type of coercion. The attacker only needs to maintain physical control long enough for a transaction to confirm. On Bitcoin that takes minutes.
Security professionals and industry leaders have consistently recommended two practical mitigations. Multisignature wallet setups require multiple keys to authorize a transaction, meaning a holder under duress cannot unilaterally complete a transfer without the cooperation of a second key holder in a separate location. Maintaining a low public profile reduces the probability of being identified as a target in the first place. Neither measure eliminates the risk. Both raise the operational complexity for attackers significantly.
France’s 19 incidents in 2025 suggest that raising that complexity has not yet deterred organized criminal networks that have identified crypto holders as high-value, low-institutional-protection targets.
