Across social media, far-right activists and politicians have spread the names of individuals they claim were involved in the killing of Quentin Deranque, a 23-year-old far-right activist who was fatally beaten by a group of youths in the city of Lyon on 12 February and died two days later.
A flood of conflicting narratives and misinformation about the suspect's identities, as well as false images of Deranque, spread online before the first arrests were made.
