Overview

• Grégory Doucet, the ecologist mayor of Lyon, was placed in garde à vue on April 9, 2025, as part of a financial investigation into alleged public funds misappropriation.
• The investigation focuses on whether municipal positions, such as chargés de mission, were improperly used for political activities instead of administrative functions.
• Authorities previously conducted a perquisition at Lyon's Hôtel de Ville in March 2024, following a report from the Chambre régionale des comptes in 2021.
• Doucet's spokesperson emphasized that the mayor is fully cooperating with the judicial process and continues to perform his duties as mayor.
• This development comes less than a year before the 2026 municipal elections, intensifying political scrutiny of Lyon's ecological leadership.
