Four men from the Paris region have been placed under formal investigation for their involvement in a cryptocurrency extortion case that began with the kidnapping of a family in Ploudalmézeau, Finistère, in April 2026. The suspects, aged between 18 and 37, were known to the police and were arrested in late August after a multi-day operation that involved 40 law enforcement officers from various units. Two of the men were placed in provisional detention, while the other two were placed under judicial supervision. The incident began when five family members — two grandparents, their daughter, and her two children — were kidnapped from their home in Ploudalmézeau on April 20. The victims were found by neighbors who alerted the gendarmerie after discovering them inside the house. The kidnappers had tied up the victims and demanded access to a digital wallet containing approximately 700,000 euros in cryptocurrency. The father of the family, who was described by prosecutors as being active in the cryptocurrency field, was not present during the kidnapping. The Rennes prosecutor’s office confirmed that a judicial investigation was opened in mid-June 2026. During the operation to arrest the suspects, law enforcement conducted searches in Bandol (Var), Paris, and Sevran (Seine-Saint-Denis). The suspects were charged with offenses including armed organized theft, kidnapping, and participation in a criminal association. The case has drawn attention due to the use of cryptocurrency as a means of extortion, a relatively new challenge for law enforcement. The kidnappers reportedly obtained the password to the family’s digital wallet through coercion, highlighting the growing intersection between traditional crimes and digital assets. Prosecutors emphasized that the suspects had prior knowledge of the family and the victim’s involvement in cryptocurrencies, suggesting a targeted approach. The case underscores the evolving nature of criminal activity in the digital age.
