French authorities have arrested four people in connection with the death of 23-year-old student Quentin Déranque, who died after suffering severe brain injuries last week in Lyon. According to local reporting, those detained on Tuesday include Jacques-Élie Favrot, a parliamentary assistant to radical leftist legislator Raphaël Arnault, and Adrian Besseyre, a former intern for Arnault.
Déranque was providing informal protection for a protest organized by the right-wing feminist group Collectif Némésis outside Sciences Po Lyon, where a lecture by far-left Member of the European Parliament (MEP) Rima Hassan of La France Insoumise (France Unbowed/LFI) was taking place. The French press has previously indicated that six suspects identified by investigators are affiliated with the Jeune Garde, an Antifa-linked gang in Lyon that Arnault helped found before his election. Although the French government moved to ban Jeune Garde last year for inciting violence, questions remain about whether the cell truly disbanded or continues to operate.
The case has triggered fierce political condemnation. National Rally president Jordan Bardella said: “A parliamentary assistant to the LFI MP Raphaël Arnault is among those arrested in the investigation into the death of Quentin. Jean-Luc Mélenchon bears immense moral and political responsibility: his complicity with ultra-leftist groups, which he himself describes as ‘young comrades,’ has opened the doors of the National Assembly to presumed murderers.” Justice Minister Gérald Darmanin stated that “the Young Guard kills, and La France Insoumise should condemn it.”
Footage circulating online has also shown some on the left allegedly celebrating the fatal attack, with one individual shouting: “I’m in favour of Quentin’s death!” Figures such as Marine Le Pen have renewed calls to formally classify Antifa as a terrorist organization.
In recent years, Antifa-linked actors have been involved in high-profile violent confrontations in Europe and the United States. A violent transgender Antifa radical in Hungary was sentenced to eight years in prison earlier this year for hammer attacks on people perceived as right-wing that took place in 2023. Meanwhile, President Donald J. Trump, last November, declared several European Antifa groups as foreign terrorist organizations.
In the United States, the Trump administration designated Antifa as a domestic terrorist organization in September 2025, characterizing the movement as a “militarist, anarchist enterprise” that uses violence and intimidation to pursue political goals, and calling for federal resources to counter its activities. So far, very few European governments have pushed for similar designations.
