The short version

A 16-year-old boy has been sentenced to four and a half years in youth detention after being convicted of wounding with intent for stabbing history teacher Vicki Williams at a school in Pembrokeshire, Wales.
The teacher sustained wounds to her head, back, and hands during the February attack, and stated in court that she is suffering from PTSD and has been unable to return to teaching.
The sentencing judge raised concerns about potential copycat violence against educators following another school stabbing incident in south-west Wales in 2024.
