A 16-year-old boy has been sentenced to four and a half years in youth detention for stabbing his teacher in the head with a kitchen knife at a secondary school in Pembrokeshire, Wales — an attack she told the court made her fear she would die.
The attack
Teacher Vicki Williams was attacked Feb. 5 at Milford Haven Comprehensive School after the boy asked her to check his homework in an empty classroom at the end of the day, according to evidence heard at Swansea Crown Court. He closed the door, searched through his bag, asked if his work was correct, then pulled a large kitchen knife from the bag and stabbed her in the head. Williams said the attack “came out of nowhere.” She grabbed the knife, pushed the boy away with her legs and screamed for help. She was treated at a hospital in Haverfordwest for a scalp wound along with scratches to her back and minor cuts to her hands, and said the boy looked at her with “pure hatred.”
CCTV footage played at trial showed the teenager running from the school afterward. He was later found at his grandmother’s house, where he reportedly told her “something went” in his head. He cannot be named due to a court order.
Trial and verdict
Following a trial in July, the boy was acquitted of attempted murder but convicted of wounding with intent. He had already pleaded guilty to possessing a bladed article on school premises. At trial, he told the jury he’d brought the knife to school as part of a “game” with friends involving bringing random household objects to see what they could “get away with,” and said the stabbing was “an accident.”
Sentencing
Judge Paul Thomas KC said there had been a “significant degree of planning” and that “time stood still” for Williams. “What I do know for certain is that you took a knife that day to school because you wanted to really hurt her with it,” the judge said, adding it was “pure luck” her injuries weren’t far worse, even fatal. He referenced a 2024 case at Ysgol Dyffryn Aman, where a teenager stabbed two teachers and a pupil, calling this the second such Welsh case in recent years: “The court have to try and keep teachers safe from attacks. I want anyone who is ever thinking of doing the same to know what will happen to them.”
Defense counsel Matthew Roberts described his client as previously of “clean character” and “well behaved,” who had made “excellent progress” in detention. He’s expected to be released after serving half his sentence, though that could shift with changes to early-release rules.
The teacher’s account
Williams said she doesn’t know if she’ll be able to return to teaching and begins PTSD therapy this week. In her victim statement, she described feeling “sadness, anger and guilt,” saying her daughter had “almost been left without a mum,” and that leaving teaching “should have been my choice to make.” Returning to the school over the summer, she said she realized how closely she’d been pinned against the wall during the attack; a colleague who came to her aid described her screams as “gut-wrenching.”
Crown Prosecution Service’s Jonathan Pritchard called it a “shocking display of violence” against “a teacher doing their job.” The Welsh government said violence in schools is “completely unacceptable” and pointed to a framework in development to address behavioral incidents and wellbeing.
The boy has been convicted and sentenced; the case was not reported as subject to further appeal.
