Four men bound a French family for three hours to extract a 40,000-euro crypto transfer
Four hooded men entered a house near Lens at 4 a.m. on Sunday and left more than three hours later with 40,000 euros in crypto taken from a salaried IT worker. Bethune prosecutors are treating it as organized extortion.

What happened
- Four hooded men broke into a detached house on the rue Simone Veil in Vendin-le-Vieil, near Lens, at around 4 a.m. on Sunday, September 20, and tied up a couple and their two children with black tape.
- Prosecutors said the father, a 40-year-old salaried IT worker in the crypto sector, was insulted, threatened and beaten until he gave up his login details, then transferred 40,000 euros in cryptocurrency.
- The men stayed more than three hours before driving away; the family worked itself free and firefighters took over from 7 a.m., and all four suspects are still at large.
- The Bethune prosecutor's office opened an investigation into unlawful detention of several people and extortion by an organized gang, and referred the victims, described as in shock, for forensic examination.

Why it matters
- exposure An identifiable crypto job is now enough to qualify a household as a target; the earlier French cases that Decrypt lists needed a public fortune, an exchange chief or a founder's family.
- cost A robbery of this size pulls in France's Anti-Cybercrime Office alongside the Pas-de-Calais and Nord judicial police, so national specialist capacity is being consumed case by case at the low end.
- constraint Custody that rests on one person's codes does not survive three hours of coercion in the house those codes are reachable from; the codes were the only control on the transfer, and the coercion reached them once the father spoke.
- contradiction Chainalysis counted 30 million dollars taken in 2026 and CertiK put losses at 124 million across six months, four times as much on a shorter period; against the 52 verified first-half attacks those imply average takes of 577,000 and 2.4 million dollars, versus 46,000 here.
Split four ways, the take comes to 10,000 euros a man [1]. The charge, unlawful detention of several people and extortion by an organized gang, can carry up to 20 years in prison [2]. That price implies the four did not have to go looking for the house.
Decrypt's list of earlier French victims runs to the father of a crypto millionaire whose finger was severed, the wife of a Sandbox co-founder and the chief executive of Binance France [15]. This house held a 40-year-old salaried IT specialist in the crypto sector, his 41-year-old partner, a 12-year-old daughter and an 8-year-old son [3]. The men searched it, then separated the father and assaulted him, making him "communicate his identification information and codes", a police source told France Televisions [9]. The two accounts of the assault on the daughter differ. Cryptopolitan's police source said she was struck on the back of the head to wake her [22]; Decrypt cited a source close to the investigation saying she was struck in the face with car keys [23].
PNACO, the national organized-crime unit, tallied 18 crypto-linked cases in 2024 [11]. Interior Minister Laurent Nunez said in July that France had registered 77 kidnapping, detention and extortion cases linked to crypto by the end of June, against 45 for all of 2025 [10]. Monthly, that is 1.5 cases in 2024, 3.75 in 2025 and about 12.8 in the first half of this year. The current pace runs roughly 3.4 times the 2025 rate and about 8.6 times the 2024 rate [2].
A hacker was marketing tax records on more than 678,000 French individuals and companies stolen from the tax authority DGFiP, Cryptopolitan reported in August [18]. A DGFiP official is accused of querying crypto-holder profiles in government software and selling the data to criminal networks [19]. Cryptopolitan attributes the link between those leaks and the surge in attacks to analysts [20]. Neither publisher connects this family to either leak.
I would expect the move down-market to hold. The cost of identifying a household with 40,000 euros in reachable crypto falls every time a list like that circulates, and the take no longer has to be large to justify a night's work. Two readings sit against that. The 2024 tally and the 2026 tally come out of different counting exercises. France accounted for 33 of the 52 verified wrench attacks worldwide in the first half of 2026, about 63.5 percent of the total [14], and that share may be measuring French disclosure as much as French crime. Then there is enforcement: 88 people charged, some of them minors [12]. What would prove the thesis wrong is a second half of 2026 in which the French count falls while the leaked lists are still in circulation.
What to watch
- Whether the four men are identified and arrested, and what the judicial police say about how the house was selected.
- Whether prosecutors charge the DGFiP official accused of selling crypto-holder profiles, and whether any specific attack is tied to that data.
- Whether Chainalysis and CertiK reconcile their full-year 2026 wrench attack loss counts, which currently differ by about four times.
