French police on Tuesday, February 17, arrested nine people in connection with the killing of a far-right activist.
Quentin Deranque, 23, died last week after suffering a severe brain injury when he was attacked by at least six individuals on the sidelines of a far-right protest in the southeastern city of Lyon. The demonstration was held against a left-wing politician speaking at a university.
The case has intensified tensions between France’s far right and hard left ahead of municipal elections in March and the 2027 presidential race, in which the far-right National Rally (RN) is widely viewed as having its strongest chance yet of winning power.
Lyon prosecutor Thierry Dran first announced the arrest of four suspects before confirming five more detentions, bringing the total to nine.
A source close to the investigation, speaking anonymously, said an aide to Raphael Arnault, a lawmaker from the hard-left France Unbowed (LFI), was among the initial four detained. Arnault said he had dismissed the assistant.
LFI leader Jean-Luc Melenchon said those responsible had “dishonoured” themselves by acting with apparent lethal intent. “When it comes to violence, whether defensive or offensive, not all blows are permitted,” he said.
An anti-immigration collective known as Nemesis, which says it seeks to combat violence against Western women, stated that Deranque had attended the protest to protect its members. The group blamed the killing on La Jeune Garde (Young Guard), an anti-fascist youth movement co-founded by Arnault before his election to parliament.
La Jeune Garde — dissolved in June — denied any involvement in what it called “tragic events,” while Arnault described the killing as horrific.
On Monday, February 16, National Assembly speaker Yael Braun-Pivet said one of Arnault’s aides had been barred from parliament after being cited by witnesses.
Another source close to the investigation described Thursday’s incident as “a pitched battle between members of the far left and the far right.” Footage aired by TF1 appeared to show around a dozen people beating three individuals on the ground, two of whom managed to flee. A witness told AFP that “people were hitting each other with iron bars.”
Lawmakers observed a minute of silence on Tuesday at France’s National Assembly in Deranque’s memory. A march in his honour is expected to take place in Lyon next Saturday.
While government officials have pointed to LFI and La Jeune Garde, the Lyon prosecutor declined to comment on those allegations, stating only that the case is being investigated as voluntary homicide and aggravated assault.
On the far right, RN presidential hopeful Marine Le Pen condemned the “barbarians responsible for this lynching.” Her party leader, Jordan Bardella, said LFI’s Melenchon bore “moral and political responsibility,” accusing him of having “opened the doors of the National Assembly to suspected murderers.”
Opinion polls currently place the far right ahead in projections for the 2027 presidential election, when centrist President Emmanuel Macron will be required to step down after serving the maximum two consecutive terms.
