On 12 February 2026, Quentin Deranque, a 23-year-old French far-right activist, was beaten by several far-left individuals in what has variously been described as a "brawl" between members of the far-right and the far-left, or as a "lynching", in Lyon, France. Deranque was there "to provide security" for the femonationalist group Collectif Némésis. Many of the arrested individuals were linked to the outlawed far-left militant anti-fascist collective Jeune Garde Antifasciste (English: Anti-Fascist Young Guard). Deranque died from brain injuries two days later in hospital.
Deranque's death, initially reported as an attack on an isolated victim, rather than a brawl between two armed groups, provoked national political reactions in the lead-up to the March 2026 French municipal elections and a minute of silence held in the National Assembly. Politically, Deranque's death led to the isolation of left-wing party La France Insoumise (LFI), as the party was close to the Jeune Garde. On 17 February 2026, LFI leader Jean-Luc Mélenchon reiterated his party's "great affection" for the Jeune Garde. In late February 2026, Mélenchon accused the far-right feminist collective Némésis of having deliberately organised a "trap" (traquenard) by using its members as bait to provoke clashes with antifascist militants around Rima Hassan's conference in Lyon.
Part of the French political class accused the far-left, or the ultra-left, of being responsible, while the public prosecutor office and the police sought to identify the perpetrators. Justice minister Gérald Darmanin and interior minister Laurent Nuñez both commented on the early progress of the investigation, claiming that the far-left was behind the attack. Citing videos of the event, several journalistic investigations gradually called into question the initial version of events by Némésis, particularly regarding who was responsible for the clashes between the two groups. Further investigations revealed that Némésis had repeatedly coordinated with far-right groups in Lyon to provoke clashes with left-wing activists.
Quentin Deranque
Deranque, originally from Saint-Cyr-sur-le-Rhône, Rhône department, was the 23-year-old son of a French father and a Peruvian mother. He was a mathematics student and far-right identitarian activist, belonging to the neo-fascist group Allobroges Bourgoin, based in Isère, and a former member of Action Française, according to Mediapart. The newspaper also reported that he participated in the 2025 edition of the 9 May Committee's neo-fascist rally.
A convert to Catholicism, Deranque was reportedly a parishioner at a church in Vienne and was involved with the Priestly Fraternity of Saint Peter, a traditionalist Catholic group, and the Catholic identitarian organization . It was alleged that Deranque was acting as security to members of Némésis participating in the protest at the time of his death, which was denied by an acquaintance of Deranque, who also claimed that he was a pacifist and involved in the Saint-Martin shelter, which operates soup kitchens. Mediapart found that Deranque had been an active participant in far-right circles on Twitter between 2023 and his death. There he had described himself as a fascist, called for the Gayssot Act to be repealed, declared support for Adolf Hitler, recommended the works of Maurice Bardèche, and posted various racist and Islamophobic comments.
The only known authentic photo of Deranque was published by Le Figaro, and was provided by the family's lawyer. Many depictions of Deranque posted on social media were actually of Dylan Guichaoua, a local representative for the National Rally (RN), or of Belgian car accident victim Quentin Piron. Many of those images were modified by AI.
Context Lyon has historically been a stronghold of far-right groups in France, in particular since the 2000s, during which according to , 102 far-right violent actions have taken place.Some 102 acts of violence listed by local media between 2010 and 2025, News outlets, such as Libération in France and ABC in Spain, have characterised Lyon as the hotbed of political violence in France.
Killing On 12 February 2026, a lecture by La France Insoumise (LFI) MEP Rima Hassan was scheduled for 18:00 CET at the Institut d'études politiques de Lyon (IEP). According to the police, at , clashes broke out between two groups of demonstrators on the sidelines of a protest by the Collectif Némésis, a femonationalist organization, during which a banner reading "Islamo-leftists, out of our universities" was unfurled. Near the intersection of Boulevard Yves-Farge and Rue Victor Lagrange in the 7th arrondissement, from the lecture venue, at , a brawl between two groups started, after which Deranque was isolated and beaten by alleged antifascists while on the ground. Around 17:57, Deranque was seen lying down, unconscious, near 11 rue Victor Lagrange. After the attack, a friend tried to help Deranque home but Deranque's condition deteriorated on route. Firefighters were called an hour and a half later, at to , nearly 2 kilometres away from the scene of the confrontation. Deranque was then taken to in critical condition.
Deranque died two days later, on 14 February, from his injuries. The medical examiner who performed the autopsy stated that a major traumatic brain injury was the cause of death and determined that "the student had no chance of survival, even if he had been taken to the hospital immediately." According to , citing a source close to the investigation, two small groups of at least twenty people met a few hundred meters behind the political science school, behind the railway line. After these clashes, Deranque and another person left the area. According to the mother of a friend, as Deranque was returning home, he was isolated, beaten, then knocked to the ground, "lynched", and left for dead. The scene was filmed by a witness, and the video was circulated in the press. On 14 February, TF1 broadcast a video of the events showing about fifteen men beating three individuals.
Investigation According to press reports published in the days following the events, investigators quickly identified several suspected participants in the beating. Some were known to intelligence services due to their previous links with the Jeune Garde Antifasciste, a movement that was dissolved in 2025 by the French government.https://www.legifrance.gouv.fr/jorf/id/JORFTEXT000051724933 Public prosecutor Thierry Dran announced on 16 February that at least six people were thought to have participated in the attack on Deranque.
Between 17 and 18 February, eleven individuals associated with Jeune Garde were arrested in connection with Deranque's death, two of whom worked for MP Raphaël Arnault, the founder of the Jeune Garde and member of the left-wing party La France Insoumise. One of the arrested who worked as a parliamentary assistant for Raphaël Arnault withdrew from his duties as a parliamentary assistant "pending the investigation" while denying "being responsible" for the death of Deranque on 15 February prior to his arrest on 17 February. On 16 February, the president of the National Assembly suspended the accused's access to the Palais Bourbon, as his presence could cause "disturbances to public order". French police also stated that investigation will also cover aggravated violence against other victims during the same incident, and possibly other acts committed earlier that afternoon.
On 4 March 2026, the Rhône Territorial Crime Directorate (DCT) and the (SDAT) arrested a 23-year-old man in the Lyon area and a 26-year-old man in the Aube department. The two arrested were accused of direct participation in the beating of Deranque, according to Agence France-Presse. Both were formally charged and placed in pretrial detention on 6 March.
As part of the ongoing investigation, officers from the territorial intelligence service (Renseignement territorial) conducted surveillance near Sciences Po Lyon and took approximately fifty photographs of around fifteen antifascist militants linked to the Jeune Garde. The images documented their movements over roughly 600 metres, including the moment they donned hoods (cagoules) and gloves in preparation for the confrontation, thereby highlighting their masked character. This photographic evidence was made public by BFM TV on 27 March 2026. French authorities also seized the mobile phones of several right-wing activists who were present on 12 February.
Reactions Domestic and political reactions On the evening of Deranque's death, President Emmanuel Macron denounced "an unprecedented outburst of violence" and called for calm. A memorial gathering was organized that same afternoon in Angers. The entire political class joined the call for calm and condemned the brawl. La France Insoumise (LFI) condemned the violence and asserted that its security service was not involved. LFI became the target of political attacks because its leader Jean-Luc Mélenchon had fought against the government making the Jeune Garde an outlawed organisation, and one of its co-founders, Raphaël Arnault, sits as a LFI deputy in the National Assembly. In 2025, Mélenchon had called on LFI members to become involved with the Jeune Garde. After the Jeune Garde was outlawed by the government, LFI deputy Thomas Portes stated the Jeune Garde "will live on", while the European Parliament LFI leader Manon Aubry said: "Glory to the Jeune Garde." After Deranque's death, Mélenchon stood by his earlier comments, saying LFI had "great affection" for the Jeune Garde.In late February 2026, Mélenchon accused the far-right feminist collective Némésis of having deliberately organised a "trap" (traquenard) by using its members as bait to provoke clashes with antifascist militants around Rima Hassan's conference in Lyon. He called for the dissolution of Némésis. On 18 February 2026, the government spokesperson Maud Bregeon called on LFI to remove Arnault from its parliamentary group.
Socialist Party leader Olivier Faure stated "La France Insoumise cannot avoid a self-examination", adding the party "constantly [resorts] to excesses and [seeks] to create conflict between everything and its opposite." Former president François Hollande called on left-wing parties to no longer ally with LFI, stating that "they maintain a brutality in their expression, denunciation, accusations, excesses, and hurtful verbal formulas." Hollande was joined by Place Publique leader Raphaël Glucksmann in his call for other left-wing parties to no longer ally with LFI. The Ecologists (LÉ–EELV) leader Marine Tondelier called out LFI's "left-wing populism". Leader of The Republicans (LR) in the National Assembly Laurent Wauquiez said "it's not the police who kill, it's the far-left" and "today, the far-left has blood on its hands". Several figures and media outlets, ranging from president Macron, the government and the far-right, such as justice minister Gérald Darmanin, interior minister Laurent Nuñez, and Le Figaro, claimed that the killers were far-left. Nuñez stated on 15 February 2026 the Jeune Garde collective appeared to be "clearly" involved in the death, based on testimonies. On the evening of 15 February, a banner in tribute to Deranque was held up by Lyon supporters, probably the , shortly before the start of the football match between Olympique Lyonnais and OGC Nice.
