French police are investigating the death of a popular streamer, who died during a nearly 12-day live stream after apparently suffering abusive and humiliating treatment.

Authorities said that they are investigating not only the direct circumstances of Raphael Graven’s death but also the broader role of digital platforms in enabling dangerous content to flourish.

French government minister Clara Chappaz described Mr Graven's death and the violence he endured as an "absolute horror", adding he had been "humiliated" for months.
