A SUNRAYSIA school missed opportunities to help a teenage student who was exposed to intense online bullying before taking a fatal dose of paracetamol, a coroner has found.

Coroner Paresa Spanos found the death of Red Cliffs Secondary College student Angel Hensgen in November 2015, two weeks before her 14th birthday, followed an escalation of online bullying, but did not conclude that the girl overdosed with the intention of taking her own life.
