A furious mother who beat up a school bully who had attacked her son has apologised after she beat him senseless in front of his entire class.

The angry mum – named only as Roxana by local media in Rio Negro province, Argentina – stormed into the classroom after her son Benjamin came home covered in blood,

Phone footage of the showdown on 2nd November shows her flying at the bullying leader after her son had pointed out his gang after she shouted: “Who are they?”

As she marched into the classroom she shouted: “You have one year left to graduate, you sh*tty scoundrels.”

Then she shrugs off a teacher as she pins her son’s bully to the wall, she continues to batter knocking off his white trucker cap as he cowers in a corner.

As she grappled and slapped him she screamed: “What’s wrong with you with my son?”

Eventually, it took two grown-ups and several students – believed to be aged around 15 – to pull her away.

Videos of the showdown were shared on social media platforms, where many watchers criticised the woman for her actions.

She later apologised for her behaviour by saying: “I am going to apologise accordingly to the student and the boy’s family.

“The situation overwhelmed me emotionally, I do not justify my actions.

“It is a situation that could have been avoided a long time ago. This is not new.”

She reportedly claimed that she had already alerted the school’s management about the bully’s violent behaviour.

But, she said, they never responded so she decided to take justice into her own hands.

Roxana said: “One day he [Benjamin] came home all bloody. I reported this to the school authorities and they never gave me an answer.

“They told me that they could not intervene because they were minors.”

She said that her son had suffered “harassment in the bathroom, spitting, they ripped his clothes, they called him fat and they were going to wait for him at the exit to beat him up.”

Roxana continued: “This boy entered the middle of the year, they had already kicked him out of two other schools.

“He’s not even my son’s partner, he’s two years younger. He lives to fight.

“He got into a fight with my son two weeks ago in the street, and then he threatened him by bringing knives to the playground.”

The Ministry of Education criticised the assault and reported that they would investigate the matter.

They stated: “Education authorities in Alto Valle filed a complaint against the person who entered the establishment and physically and verbally assaulted the minor and – according to some testimonies – teachers.

“How did an adult – who does not work or attend school – managed to enter the establishment and later a classroom, without any type of authorisation?”

School director Lucas Frank said: “There are duties and rights of parents, students and teachers. What happened is not minor.”

The investigation continues.
