Teenage schoolgirl who allegedly stabbed fellow student sent chilling warning on social media

Seven News can reveal that a schoolgirl charged with stabbing a fellow student at an Adelaide college had posted a disturbing warning online days before the attack.

The teenager allegedly wrote that she had a hit list and was "ready to fire".

The school day had barely started when police converged on Trinity College in Adelaide's northern suburbs.

A teenager had allegedly brought a knife to school and attacked a 15-year-old girl, stabbing her multiple times in the stomach, arm and hand.

One student told 7 News that she heard “a girl’s been stabbed at North Campus, in the locker hallway… it was girl-on-girl.”

“Apparently she’s been saying stuff on Snapchat, so social media’s got an impact on the situation,” the student said.

Police have confirmed it was a targeted attack.

In a series of disturbing threats two days prior, the alleged stabber said she was sick of being "walked all over" in a post on social media app Snapchat.

“I’m sick of being walked over,” the girl allegedly wrote.

“I’m not sitting back and taking s*** no more. Got my hit-list lined up and ready to f****** fire.”

The shocking incident comes just two days after a plea from the parents of Seaford Secondary College student Libby Bell, who took her own life to end bullying.
