THIS is the shocking moment an enraged pregnant mum stormed into a classroom and threatened to “slit” a young girl’s throat.

Dramatic footage shows the Australian mum reaching a “tipping point” as she throws violent insults towards a 12-year-old girl who caused the outburst.

“You ever f*****g mess with my daughter again I’ll slit your f*****g throat,” the mum yelled in her dramatic outrage as she confronted the pupil.

She shouted: “I’ll be waiting for you. And that smart little **** over there, yeah, you know what, you’re just jealous because you’re a **** ****. You’re a **** ****.”

The mum revealed her reasons for her berating the young child at St. Paul’s College in Gilles Plains in Australia to 7 News.

She admitted her wrongdoing, but explained that her furious scolding only happened because her daughter had been targeted by bullies for more than a year.

She told 7 News: “I don’t want my daughter to be another statistic. I don’t want to have to bury my child.”

“She was crying, she was devastated that this child told her to go and hang herself.”

“That is a breaking point for any parent… I went into survival mode, and protective mode. I did let loose, unfortunately was a side I don’t show very often. But that was a tipping point for that day.”

She also said that the school did not properly pay attention to or resolve the issue after “begging” them for help.

“I did everything in my power as a parent and so did my husband to make sure our daughter was safe, especially dropping her off at school,” she said.

“The school has been negligent on their behalf, they have not done what they said (they’d) do. They have ignored all aspects about what we stated about the bullying with our daughter.”

“I have stated time and time again to the school that we are begging. We begged for help. We begged.”

Despite a rally of mums defending the emotional parent, she has since apologised for her behaviour.

The Adelaide woman’s actions were justified by scores of mums on social media who said they would have done the same if it were their child.

Footage of the February 3 incident, which went viral on social media, spawned a group of users who defended the mum’s actions called “Team Mumma Bear”.

South Australia Police are investigating the incident and confirmed the student who was yelled at was not physically injured, whilst St. Paul’s College said it is offering support to students who witnessed the incident.

In the video, the woman is seen being held back by a man who is believed to be her husband.

“You want to f*****g go, bitch? You want to f*****g go? You ever f*****g talk to my daughter again,” the woman shouted in front of students as the man attempted to push her away.

“I’m you f—ing worst night, bitch. I’m you worst f*****g nightmare,” she continued.

School principal Patrick Harmer said in response to the incident: “As this is subject to a police investigation, we cannot provide further detail at this stage.

“The safety and wellbeing of our students is of the utmost importance, and we are providing support to students who may have witnessed the incident.”

He also sent a letter to concerned parents of all children present at the time of the ordeal. 

He wrote: “We provide an environment where the safety and wellbeing of all is our highest priority. We will continue to ensure the best possible support for our students and staff during this time.”
