A streamer known for taking part in extreme online challenges has been found dead.

Raphael Graven, also known as Jean Pormanove or JP, died following a live broadcast at his home in Contes, a village north of Nice, on Monday.

The 46-year-old reportedly endured ’10 days and nights of torture’ including ‘extreme’ physical violence and sleep deprivation beforehand.

People watching his final stream are said to have raised the alarm after seeing him lying motionless on a mattress and not responding to any of their messages.

While he lay on the mattress, a man could be seen throwing a bottle of water at him.

Government minister Clara Chappaz described the violence Graven suffered before his death as an ‘absolute horror’ and said he had been ‘humiliated’ for months as she announced a judicial investigation is now under way.

Sarah El Haïry, the country’s high commissioner for children, similarly said the streamer’s death is ‘horrifying’ in a post on X.

She wrote: ‘Platforms have an immense responsibility in regulating online content so that our children are not exposed to violent content. I call on parents to exercise the utmost vigilance.’

Graven’s cause of death has yet to be determined, and an autopsy will take place later.
