A MANDURAH High School went into lockdown today after a gang of adults went to the school to fight students.
Initial reports suggested one of the three adult males showed up to Halls Head College this afternoon with a knife.
However, that turned out to be false.
A student said they were locked in their classrooms due to a “massive fight” on school grounds.
Police were called to attend at 1.35pm.
The adults left the school grounds and students were allowed to leave their classrooms.
This isn’t the first time the school has been in the spotlight for violence.
In August, police were called to the school to confiscate a toy gun from a student.
A teacher was charged with assaulting a student in September.
