Overview

• On December 22, 2024, the suspected mastermind, a 27-year-old with prior narcotics convictions, was arrested at Osvaldo Vieira Airport in Guinea-Bissau under an Interpol warrant.
• France’s extradition request remains pending as Guinea-Bissau has not decided on transferring him due to the absence of a bilateral agreement.
• A sixth suspect implicated in coordinating the arson logistics was arrested in Algeria on April 23, 2025, but the 2019 France-Algeria treaty bars his transfer to France.
• Investigators previously detained four individuals in France who have been indicted and placed in pretrial detention for roles in the July 2024 fire that killed seven family members in Nice.
• French prosecutors are continuing to identify collaborators and are relying on international cooperation and digital surveillance to advance the cross-border investigation.
