Milford Haven teen, 16, jailed four-and-a-half years for stabbing teacher in head
A 16-year-old boy has been sentenced to four-and-a-half years in youth detention for stabbing teacher Vicki Williams in the head with a kitchen knife at a Pembrokeshire school.

Milford Haven pupil sentenced over classroom knife attack on teacher
A 16-year-old boy has been sentenced to four-and-a-half years in youth detention after stabbing his teacher in the head with a kitchen knife at Milford Haven Comprehensive School in Pembrokeshire, Google News IE — Crime (en) reports, citing BBC coverage of proceedings at Swansea Crown Court.
Vicki Williams was attacked on 5 February after the pupil asked her to check his homework at the end of the school day. He followed her into an empty classroom, closed the door behind him, and pulled a large kitchen knife from his bag as he asked whether his work "was correct". He then stabbed her in the head.
Williams grabbed the knife, pushed the boy back with her legs, and screamed. She sustained injuries to her head, back, and hands. A colleague who rushed to the scene described her screams as "gut-wrenching". CCTV footage later showed the teenager running from the school.
He was subsequently detained at his grandmother's house, having told her that "something went" in his head.
'Pure luck she was not more seriously hurt'
Sentencing on Thursday, Judge Paul Thomas said it was "pure luck" Williams had not suffered worse or even fatal injuries. He told the court there had been a "significant degree of planning" and that "time stood still" for Williams during the assault.
"I don't know why you attacked Mrs Williams with that knife — you never told anybody why you did it," Thomas said. "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 noted the boy was aware he was "bigger and stronger" than the teacher.
In July, following trial, the boy was found not guilty of attempted murder but guilty of wounding with intent. He had previously pleaded guilty to possessing a bladed article on school premises. During the trial he told the jury he had brought the knife to school as a "game" with friends, involving bringing "random household objects" to see what they could "get away with", and claimed the incident was "an accident".
Teacher describes lasting trauma
In her victim personal statement, Williams said she felt "sadness, anger and guilt" in the aftermath of the attack. "I focus too much on what could have happened to me," she said. "My daughter had almost been left without a mum."
She said she did not know whether she would be able to return to work and is due to begin therapy for post-traumatic stress disorder this week. During the summer holidays she revisited the classroom with a colleague and realised how closely she had been "pinned" to the wall behind her desk.
"My fellow teachers and I don't deserve this because we work so hard," she said. "I didn't ask for this. Leaving teaching should have been my choice to make."
Defence and prosecution responses
Matthew Roberts, defending the boy — who cannot be named due to a court order — said he was of "clean character" and "well behaved" prior to the incident, and had made "excellent progress" since being placed in youth detention. The boy's family were present in the public gallery as he stood in the dock wearing a blue shirt.
Jonathan Pritchard of the Crown Prosecution Service described the attack as a "shocking display of violence" against "a teacher doing their job". "The teacher showed great courage in what must have been a terrifying incident," he said.
The boy is expected to be released after serving half of his sentence, though the court noted the release date could change depending on potential amendments to the early release scheme.
Second school stabbing in south-west Wales
Judge Thomas also referenced a separate incident at Ysgol Dyffryn Aman in south-west Wales, where a teenager stabbed two teachers and a pupil in April 2024. "The court has to try and keep teachers safe from attacks," he said. "This is the second case of a school pupil stabbing a teacher in a school in the last couple of years. I want anyone who is ever thinking of doing the same to know what will happen to them."
The Welsh government issued a statement saying that "any form of violence or abuse in our schools is completely unacceptable" and that ensuring school safety was "a key priority". It added that work had already begun on developing a framework with partners to support schools in tackling poor behaviour, attendance issues, and pupil wellbeing.
