“It was clearly the ultra-left that killed him,” Darmanin told RTL television.
“There are indeed speeches, particularly from France Unbowed and the ultra-left, which unfortunately lead to unbridled violence on social networks and then in the physical world,” he said.
“Words can kill,” Darmanin added, accusing Hassan and LFI leader Jean-Luc Melenchon of “not having a word to say for the family of the young man”.
‘Compassion, respect’
Later, Melenchon voiced his “shock” at the killing.
“We also send our empathy and compassion to his family and loved ones,” he said.
Melenchon, a three-time presidential candidate widely expected to run again in elections next year, added that his movement opposes violence, rejecting the blame placed on it as lacking “any connection with reality”.
An alleged video of the attack broadcast by TF1 television shows a dozen people hitting three others lying on the ground, two of whom manage to escape.
“I heard shouts, people were hitting each other with iron bars and so forth. When I came to the scene, I saw individuals covered in blood,” a witness to the attack, who gave only the first name Adem, told AFP.
According to the Nemesis collective, which is close to the far-right, Deranque was providing security for its protesters and was assaulted by “anti-fascist” activists.
The family’s lawyer said in a statement that Deranque appeared to have been ambushed by “organised and trained individuals, vastly superior in number and armed, some with their faces masked”.
Pre-election tension
The incident has further fuelled tension between France’s far-right and far-left ahead of municipal elections nationwide in March and the 2027 presidential race.
Three-time presidential candidate Marine Le Pen, who is still hoping to stand in 2027 despite a graft conviction, said on X that the “barbarians responsible for this lynching” should be brought to justice.
Demonstrations called by the far-right in memory of Deranque took place in the southern city of Montpellier and Paris, where protesters unfurled a banner reading “antifa murderers, justice for Quentin”.
The far-right has pointed the finger at la Jeune Garde (Young Guard), an anti-fascist youth offshoot of the LFI.
But its founder Raphael Arnault, an LFI lawmaker, expressed his “horror” at the fatal beating, and the group denied involvement, saying it had “suspended all activities”.
LFI lawmaker Eric Coquerel, speaking to Franceinfo, condemned “all political violence” but said the activists responsible for Hassan’s security “were in no way involved in what happened”.
He pointed instead to a particular “context” in the southeastern city marked by violence from “far-right groups”.
Centrist President Emmanuel Macron has called for “calm” and “restraint”.
At Saint George’s Church in Lyon, which the man attended and where he volunteered for charities, priest Laurent Spriet called for prayers “for the peace of Quentin’s soul”.
“Everything in its own time. Now is for compassion, for respect, for prayer, for letting the police and the justice system do their work,” he said.
