'I was shaking, crying': Mother of stabbed student takes aim at high school

The mother of a 15-year-old girl that was stabbed at her western Sydney high school has taken aim at Bonnyrigg High School after they failed to contact her.

The shocked mum took to Facebook to share confronting photos after her daughter, a fellow Year 11 student and a teacher were all stabbed at the start of the school day on Thursday morning.

“(I) was so shocked this morning when I heard that my daughter was stabbed to the back at school this morning with a metal ruler,” the mum wrote.

“When I heard the news this morning about my daughter I was shaking, crying and most of all worried about my daughter.

“The thing that upsets me even more is that the school did not contact me or the emergency contact number that I provided to them when they were supposed to contact me immediately as soon as it happened."

The teenage girl suffered a stab wound to the back of her shoulder and was rushed to The Children’s Hospital at Westmead, while the male student and 48-year-old teacher, Carolyn Cox were both rushed to Liverpool Hospital after being stabbed in the chest and back respectively.

After arresting the alleged attacker, NSW Police confirmed that he had been charged with causing wounding with intent to murder and two counts of wounding a person with intent to cause grievous bodily harm.

He is now due to front court on Friday after he was arrested in a nearby car park shortly after police were called to the high school.

“Please parents be aware of what is happening at your child’s school. I hope that this does not happen to anybody else’s kids,” the mum added.

All three victims are in stable conditions at the two hospitals, with police describing their wounds as non life threatening.

Meanwhile, Ms Cox is being praised for her heroic attempts to prevent the stabbing.

"He is not known to New South Wales Police," Fairfield Police Superintendant Peter Lennon said yesterday.

"The Department of Education is setting up welfare services for those students to take care of them and the teachers."
