Jury hears teenager allegedly brought kitchen knife into school before teacher was stabbed in the head

THE JURY in the trial of a 15-year-old boy accused of attempting to murder a Milford Haven teacher has this afternoon heard the prosecution’s detailed account of the alleged classroom attack.

The teenager, who cannot be named because he is under 18, denies attempting to murder Vicki Williams at Milford Haven Comprehensive School on Wednesday, February 5, 2026.

Opening the case at Swansea Crown Court, Christopher Rees KC told jurors that the boy had brought a large kitchen knife into school in his bag before allegedly following Miss Williams into an empty classroom shortly after 3pm.

The prosecution alleges the teacher was alone and vulnerable when the defendant entered the room and launched what Mr Rees described as a “planned and murderous attack”.

Jurors were told Miss Williams suffered a penetrating stab wound to the top of her head, as well as injuries to her hands during a struggle for the weapon. The court also heard she sustained scratches and grazes to her back.

Mr Rees told the court: “The prosecution say the defendant planned and launched a murderous attack on the teacher. He deliberately stabbed Vicki Williams in the head.”

The court heard that Miss Williams shouted for help, after which the defendant ran from the classroom.

Emergency services attended the school and Miss Williams was treated at the scene before being taken to hospital. She was discharged later the same evening.

The alleged attack led to a temporary lockdown at Milford Haven Comprehensive School and caused widespread concern among parents, pupils and staff in the town.

This morning’s proceedings included jury selection and legal discussions before the prosecution opened its case shortly after midday. A jury of 12, along with an alternate juror, has been sworn in.

The defendant denies attempted murder, inflicting grievous bodily harm with intent, and unlawful wounding. He has previously admitted possessing a bladed article.

Matthew Roberts KC is representing the teenager. The trial is being heard before Judge Paul Thomas KC and is expected to last up to three weeks.

The court is expected to hear further evidence over the coming days about the circumstances leading up to the incident, the injuries suffered by Miss Williams, and the explanation put forward by the defence.

The trial continues.

Swansea Crown Court hears dramatic opening of trial over February stabbing

A 15-YEAR-OLD boy from Milford Haven has gone on trial accused of attempting to murder a teacher in what prosecutors described as a “planned and murderous attack” inside a classroom.

The teenager, who cannot be named for legal reasons, is alleged to have stabbed teacher Vicki Williams in the head with a large kitchen knife during an incident at Milford Haven Comprehensive School on Wednesday, February 5, 2026.

Opening the case at Swansea Crown Court on Monday (July 6), Christopher Rees KC told the jury the defendant had brought the weapon into school in his bag before targeting the teacher.

“The prosecution say the defendant planned and launched a murderous attack,” he said. “He deliberately stabbed Vicki Williams in the head.”

Struggle in the classroom

The court heard the incident unfolded at around 3:10pm when the boy allegedly followed Miss Williams into an empty classroom.

During a struggle, he is said to have pushed her into a chair as she attempted to seize the knife. The court was told she sustained a penetrating wound to the head, along with defensive injuries to her hands and additional scratches and grazes.

When Miss Williams shouted for help, the defendant fled the scene.

Emergency services attended and the teacher was taken to hospital but discharged later the same evening.

Charges denied

The defendant denies attempted murder, inflicting grievous bodily harm with intent, and unlawful wounding. He has previously admitted possessing a bladed article.

A jury of 12, along with an alternate juror, was sworn in before Judge Paul Thomas KC. The trial is expected to last up to three weeks.

Matthew Roberts KC is representing the defence.

Community impact

The incident sent shockwaves through the Milford Haven community and prompted a temporary lockdown at the school on the day.

At the time, parents raised concerns about knife awareness, pupil wellbeing, and staff safety in secondary schools.

Dyfed-Powys Police previously confirmed the arrest of a 15-year-old boy on suspicion of attempted murder following the incident.

Pembrokeshire County Council and school leaders have said the welfare of pupils and staff remains a priority, but fuller details of any internal review have not been disclosed while criminal proceedings are ongoing.

The trial continues.

A HAVERFORDWEST man has been found not guilty of rape and assault by penetration following a trial at Swansea Crown Court.

Jack Branston, 22, of Gerald Road, Haverfordwest, was unanimously acquitted by a jury of both charges.

The allegations related to events said to have taken place during the summer of 2023. Mr Branston denied both offences throughout the proceedings.

Following the jury’s verdicts, Judge Geraint Walters formally discharged Mr Branston.

Dyfed Thomas represented the defendant, while Robin Rouch prosecuted.
