In late August, a family in the French region of Ille-et-Vilaine was mistakenly held by criminals who believed they were in possession of cryptocurrencies. The family was detained at their home in Vern-sur-Seiche, a rural area south of the city of Rennes. The criminals had targeted them thinking they were involved in cryptocurrency transactions, but the local prosecutor’s office confirmed that the family did not own any cryptocurrencies. After realizing their error, the criminals fled the scene. The incident came to light recently when authorities launched an investigation into kidnappings and detentions. The case has been assigned to the Rennes research section, which is now looking into the circumstances surrounding the mistaken detention. The family was held at their home, which is located in a quiet, rural setting, adding to the unusual nature of the event. This case is part of a broader trend of criminal activity targeting the cryptocurrency sector. Last June, France’s Interior Minister Laurent Nuñez announced plans to enhance security measures for individuals and businesses involved in cryptocurrency transactions. These measures were introduced in response to a sharp rise in criminal cases targeting the sector, with approximately 100 cases reported so far this year. This represents a significant increase compared to the same period in 2025, highlighting the growing threat posed by organized crime in this area. The mistaken detention of the Breton family underscores the risks faced by those involved in the cryptocurrency industry, as well as the potential for confusion and error in criminal investigations. Authorities are now working to identify the individuals responsible for the incident and to prevent similar occurrences in the future.
