French prosecutors have opened an investigation into the Australian streaming platform Kick after an online star died on camera following 'ten days of torture and humiliation'.

The probe, announced on Tuesday, will examine whether Kick 'knowingly' broadcast 'videos of deliberate attacks on personal integrity,' Paris prosecutor Laure Beccuau said, after the death of Raphael Graven.

The 46-year-old Frenchman had appeared in live shows on the platform in which he was abused or humiliated.

In a separate announcement, France's minister for digital affairs, Clara Chappaz, said the government would sue the platform for 'negligence' over its failure to block 'dangerous content'.

It comes as the grim studio where live 'trash' streamer Jean Pormanove died after being humiliated and tortured live on air for 12 days was revealed.
