French authorities arrested five suspects between September 7 and 8 in connection with a cryptocurrency-linked kidnapping and extortion case spanning the Paris region, Isère and Brittany. The investigation began after a March 2026 home invasion in Taninges, Haute-Savoie, where two masked men allegedly entered a 48-year-old woman’s home with a knife, tied her up and assaulted her for several hours. The attackers sought valuables and crypto assets and coerced her into transferring cryptocurrency under duress before attempting to use her vehicle to abduct her. She escaped and sought help from a neighbor. Four suspects were formally charged with unlawful confinement and attempted extortion, while three were placed in pre-trial detention as the investigation continues.
