In Nantes, ten individuals were arrested on Sunday evening and are suspected of damaging a site where a new administrative detention center is planned. The suspects are accused of driving nails into trees that were scheduled to be cut down as part of the construction of a new CRA, or Center for Administrative Reception. This facility is intended to house 140 foreign nationals in an irregular immigration status. The building permit for the CRA was issued on August 18, but the project has faced controversy from the outset. According to local police, the act of driving nails into the trees could have caused technical issues or even injuries to workers who were planning to cut them down. This type of sabotage is not new in France. Earlier in 2026, a similar incident occurred on January 19 in Mérignac, Gironde, where a site for another CRA was damaged. The Bordeaux prosecutor's office confirmed the incident, and the investigation into that case was handled by the interdepartmental police directorate (DIPN 33). The current investigation in Nantes has also been assigned to DIPN 33, which is responsible for handling such cases across multiple departments. The directorate aims to identify those responsible for the sabotage to ensure the safety of workers and the smooth progress of the project. These incidents highlight the ongoing tensions surrounding the construction of administrative detention centers in France, which have become a point of contention for various groups concerned with immigration policies and human rights. The CRA projects, while aimed at managing the immigration process, have drawn criticism and resistance from activists and local communities. The recent arrests and the history of similar incidents suggest that these facilities continue to be a source of social and political debate across the country.
