Source text: UK authorities have sentenced five individuals involved in a violent "wrench attack" on a cryptocurrency holder in Shoreditch, London. The group forcibly took the victim to their home in July 2025, using threats and facial recognition to access his bank and crypto accounts, stealing over £10,000 in cash, cryptocurrency, and a watch. The investigation was aided by Coinbase, which reported unusual activity on the victim's account, leading to the suspects' arrest. Four main offenders received prison sentences ranging from three and a half to six and a half years, while another was sentenced to community service for money laundering. Police emphasized the psychological impact on the victim and the increasing threat of physical crimes targeting crypto holders.
