A series of violent home invasions in the United Kingdom has underlined a dangerous side of cryptocurrency custody that no private key can defend against: physical coercion. In Solihull, a businessman named James told the BBC that three masked intruders forced their way into his home and beat him with hammers for around 45 minutes, striking his face, head, and ribs, while his wife—seven months pregnant at the time—was held down on a sofa and threatened. The attackers demanded his phone and appeared to receive instructions through a live video call from someone who identified a wallet holding substantial funds. James said he was told that if he did not transfer the cryptocurrency, the men would ‘stab your wife in the stomach and kill your baby.’ The robbers escaped with the funds and several Rolex watches.
In a separate incident in Tadworth, Surrey, police reported that three hooded individuals broke into a residence around 9:00 PM on Thursday, September 24, and threatened a pregnant woman and her one-year-old child to obtain security passwords and crypto wallet access. Surrey Police said the attackers fled with mobile phones and laptops. Paramedics assessed the mother and child at the scene and confirmed no serious physical injuries. Detective Chief Inspector James Ansell said preliminary findings suggest the intruders had prior intelligence about digital asset holdings at the address, indicating a planned rather than opportunistic attack.
These cases reflect a broader pattern increasingly described as wrench attacks, where criminals use violence or threats to bypass digital security. Chainalysis research cited by the BBC recorded $30 million (£22.6 million) stolen in violent crypto robberies through June 2026, with the United States, Brazil, and Thailand identified as hotspots and France recording the largest number of attacks in that data. CertiK separately logged 52 verified wrench-attack incidents worldwide in the first half of 2026, with roughly $124.1 million in recorded exposure. The firm noted its figures cover verified public incidents and are not a complete crime census.
Security researchers warn that the physical safeguards protecting traditional wealth do not automatically apply to self-custodied crypto. Once a coerced transfer is made, recovering funds on an irreversible blockchain is extremely difficult. Experts advise limiting public disclosure of holdings, separating funds, and considering multisignature arrangements, though no setup guarantees protection from violence. Personal safety, they stress, must come first.
