How the killing of a French far-right activist sparked an online manhunt

The killing of 23-year-old French nationalist Quentin Deranque, on the sidelines of a protest in Lyon, has heightened tensions between far-right and far-left groups ahead of next month’s municipal elections. Before any arrests were made, online users claimed to have identified five suspects, leading to the circulation of their personal details. But the internet sleuths got at least one case wrong: a woman identified as Blandine B., who was not even in France on the day of the killing. In this episode of Truth or Fake, Maya-Anaïs Yataghène also examines how a photo of the wrong person ended up being used in tributes to the victim.
