Mums brawl outside western Sydney school in front of young children

Police have been called in to break up a fight between two mothers outside a western Sydney school.

The feud started during school pick-up at Maronite College of the Holy Family School in Harris Park on Monday afternoon, as dozens of young children watched on.

Mobile phone footage obtained by 9NEWS shows school staff, other parents and even a nun trying to intervene as the women continue to yell at one another.

9NEWS understands the argument was over a car parking space.

The school’s principal, Sr Margaret Ghosn, released a statement on the school’s Facebook page expressing her disappointment.

“The behaviour of a number of parents was extremely inappropriate and they will be addressed accordingly,” Sr Ghosn wrote.

“I apologise for any young children who had to witness such rude and violent behaviour from adults.”

She also thanked those who stepped in to "defuse the situation, which escalated out of hand".

By the time officers attended, the fighting had stopped. There were no serious injuries and no arrests were made.

Police are continuing with their enquiries.
