A history teacher who was stabbed in the head by a pupil at Milford Haven Comprehensive School has said she is now afraid to be alone with children and does not know whether she can return to teaching. The 16-year-old boy responsible for the February attack was sentenced at Swansea Crown Court on Thursday, 3 September, to four-and-a-half years in youth detention after being convicted of wounding with intent.
The teenager, who was 15 when the attack happened and cannot be identified for legal reasons, had been acquitted of attempted murder by a jury in July. He had previously admitted possessing a kitchen knife on school premises, for which the judge imposed no separate penalty.
The case has renewed concern about school safety and knife-related violence, particularly the risks faced by teachers working alone with pupils. New Daily Prime has previously reported on another UK school-security case in which a man was jailed after taking a hatchet, knife and petrol to a Greater Manchester school.

Teacher says attack has changed her life
Vicki Williams was working at the Pembrokeshire secondary school on 5 February when the pupil approached her at the end of the school day and asked her to check some of his work.
Swansea Crown Court heard that the teenager followed her into an empty classroom, shut the door and took a kitchen knife from his bag before attacking her. Mrs Williams suffered a wound to her scalp as well as injuries to her hands and back during the struggle. She managed to disarm the boy before he fled the school.
In a victim impact statement presented at sentencing, Mrs Williams said she was struggling with the psychological consequences of the attack and did not believe she could currently return to the classroom.
She told the court: “I’m scared of being alone with the children in school.” She said even a pupil asking her for help could now trigger fear because that was how the February attack began.
Mrs Williams has also spoken about suffering post-traumatic stress disorder and taking additional security precautions at home. The attack has left her uncertain about whether she will be able to continue a profession she did not choose to leave.
Judge says more serious injury avoided by ‘pure luck’
Judge Paul Thomas KC told the teenager that it was “pure luck” Mrs Williams had not been more seriously injured or killed.
The judge said there had been a significant degree of planning and that the teenager had taken the knife to school intending to seriously hurt the teacher, although the exact reason for the attack had never been established.
The boy had told the trial that he brought the knife to school as part of a game with friends involving bringing unusual household objects onto the premises. He claimed Mrs Williams saw the knife and tried to grab it, and that she was injured accidentally during the struggle. The jury rejected that account sufficiently to convict him of wounding with intent, but cleared him of attempted murder.
The distinction is important. An acquittal on the attempted murder charge means the court did not convict the teenager of trying to kill Mrs Williams. His sentence followed the separate conviction for intentionally wounding her and his admitted possession of the knife at school.
Police initially described injury differently
The incident prompted a lockdown at Milford Haven Comprehensive School on 5 February.
Dyfed-Powys Police initially said the teacher’s injury was not a stab wound, based on the information available immediately after the incident. After further enquiries, police confirmed that the injuries were stab wounds and the teenager was charged.
Police said all pupils were safe during the lockdown and Mrs Williams was taken to hospital for treatment.
Following sentencing, Detective Inspector Sarah Totterdale praised the teacher’s bravery in having to relive the attack during the criminal proceedings and said police hoped the conclusion of the case would help her eventually find some closure.
The Crown Prosecution Service also described the case as a serious act of violence against a teacher carrying out her job and warned about the potentially fatal consequences of knife attacks.
The case forms part of a wider debate over security in educational settings. New Daily Prime has also covered concerns following a fatal school shooting in Minneapolis, where political leaders called for tighter weapons controls.
