Parliamentary Aide Detained in Connection with Far-Right Activist's Death
Eleven individuals, including a parliamentary aide affiliated with France’s hard-left party, have been arrested in relation to the fatal attack on Quentin Deranque, a 23-year-old far-right activist, an event that has deeply unsettled the nation and highlighted its intense political divisions.
Deranque, a mathematics student, was reportedly
“thrown to the ground and beaten by at least six individuals”during an incident last week, according to Thierry Dran, the Lyon prosecutor.
The assault occurred while Deranque was present on the sidelines of a protest opposing a university conference attended by Rima Hassan, a European member of parliament representing Jean-Luc Mélenchon’s left-wing party, La France Insoumise (LFI).
The anti-immigration group Némésis, which was protesting the conference, stated over the weekend that Deranque had been present to protect its members and was attacked by anti-fascist activists. Hassan and other LFI members have publicly condemned the killing.
This incident has intensified political tensions in France ahead of upcoming municipal elections and the 2027 presidential race, where the far-right National Rally (RN) is anticipated to achieve its strongest performance to date.
The initial arrests were announced late Tuesday, with Lyon prosecutor Thierry Dran confirming that nine suspects had been taken into custody. Those detained include individuals suspected of direct involvement in the violence as well as those believed to have provided support, according to sources cited by Agence France-Presse.
Subsequently, two additional suspects were arrested: a man suspected of direct involvement in the violence and his partner, who is alleged to have attempted to assist him in evading justice.
Raphaël Arnault, an LFI politician, confirmed that his parliamentary assistant was among those arrested, noting that the aide had
“ceased all parliamentary work”.
On Wednesday, following news of the arrests, LFI announced the evacuation of its national headquarters due to a bomb threat. Manuel Bompard, the party’s coordinator, stated on social media,
“The national headquarters of LFI have just been evacuated following a bomb threat. Police services are on site. All employees and activists are safe.”

As videos of the deadly confrontation circulated on social media, Jean-Luc Mélenchon urged restraint, stating on social media,
“Let’s not fuel the incitement to take the law into one’s own hands.”
Footage broadcast by TF1 depicted several individuals assaulting three people lying on the ground, two of whom escaped. A witness told Agence France-Presse,
“People were hitting each other with iron bars.”
Némésis, the anti-immigration collective associated with Deranque, attributed the killing to La Jeune Garde (Young Guard), an anti-fascist youth organization co-founded by Arnault prior to his election to parliament. La Jeune Garde, which was dissolved in June, has denied involvement in the
“tragic events”, and Arnault described the killing as
“horrific.”
While the government has specifically criticized LFI and La Jeune Garde, the Lyon prosecutor refrained from commenting on these allegations on Monday, stating that the investigation is focused on suspected
“intentional homicide”and aggravated assault.
Politicians observed a minute of silence on Tuesday afternoon at France’s national assembly in memory of Deranque. Additionally, a march is planned in Lyon next Saturday to honor him.
French President Emmanuel Macron addressed the incident in a social media post over the weekend, calling for calm and justice. He wrote,
“It is essential that the perpetrators of this ignominy be prosecuted, brought to justice and convicted. Hatred that kills has no place among us. I call for calm, restraint and respect.”
