Overview
- The main entrance hall of Lycée Nelson Mandela in Nantes was completely destroyed by a deliberately set fire during a student blockade on 1 October, footage of the blaze spreading widely online.
- Police from Nantes's Division of Organized and Specialized Crime carried out arrests on Tuesday 3 November, detaining three people reported by authorities to be pupils at the lycée; the judicial inquiry for degradation by fire remains open.
- Regional authorities have revised repair estimates upward to roughly €4–5 million and are aiming for a phased reopening that would restore most classrooms by 16 November.
- Videos circulated on platforms such as TikTok show masked individuals throwing mortiers d'artifice and a small trash fire being lit the morning of the blaze, but those clips do not replace the court process for proving who started the fire.
- The fire has left the school community of more than 1,700 students traumatized and the DCOS-led investigation signals prosecutors will treat the case as a serious criminal matter with possible juvenile justice consequences.
