The alleged incident occurred in a classroom at the Milford Comprehensive School, where a student was reportedly stabbed by a classmate.
The school was placed in lockdown on February 5, 2026, following the alleged attack.
The defendant has denied charges of attempted murder, grievous bodily harm with intent, and unlawful wounding, but has admitted possessing a blade.
According to court testimony, the alleged attack unfolded on a Wednesday afternoon when the defendant followed a teacher, Ms. Williams, into an empty classroom.
The pair became engaged in a struggle, with the defendant allegedly pushing Ms. Williams into a chair as she tried to grab the knife.
Ms. Williams suffered a stab wound to the head, defensive injuries to her hands, as well as scratches and small cuts.
She screamed for help, and the defendant fled the scene.
Emergency services responded to the school, and Ms. Williams was taken to the hospital.
She was discharged later that evening.
The school has released a statement acknowledging the distressing nature of the incident and reassuring the community that the school remains a safe and caring environment.
The school has also praised the bravery and maturity of its students and staff in responding to the incident.
The three-week trial continues.
