Boy's face showed 'pure hatred' as he attacked teacher with knife, court hears

A 16-year-old pupil allegedly lunged at his teacher in a Pembrokeshire classroom with a large kitchen knife after asking for help; CCTV shows him close the door, attack her, then run out and the school was briefly locked down.
Teacher Vicki Williams fought him off, suffered multiple cuts including a 7cm wound to her lower back, was taken to hospital, and colleagues described her screams as "gut‑wrenching."
The boy denies attempted murder; his trial at Swansea Crown Court is ongoing, with prosecutors saying the attack was deliberate and the defence arguing it was an accident.
