Overview
- A violent underground gas explosion on January 12, 2019, killed four people, including two young firefighters, injured about 200 and left roughly 400 people displaced.
- The criminal trial of the City of Paris and the building syndic opened on Tuesday, October 20, 2026, with prosecutors charging involuntary manslaughter tied to alleged municipal negligence.
- Judicial investigators found that repeated sidewalk subsidence led to a sudden rupture of a gas pipeline and that the syndic delayed repairs to a wastewater collector reported leaking on November 25, 2015.
- Technical responsibility remains contested after multiple expert reports and a 2023 counter-expertise; GRDF joined the case as a civil party but was not criminally charged.
- Victims say they still lack full compensation despite a 2022 framework agreement and expect the trial and an exceptional delayed web-radio broadcast to clarify accountability and press the city for full recognition of material and psychological harms.
