A 16-year-old has been sentenced to four-and-a-half years in youth detention after he attacked a teacher while armed with a knife in a classroom.

On 5th February this year, the teenager, then aged 15 – who cannot be named for legal reasons – followed the victim into a classroom and asked for help with schoolwork, before then attacking her.

The teacher was able to disarm the teenager, however sustained injuries requiring hospital treatment. Fortunately, she was able to make a recovery after treatment.

In July, the boy was found guilty of wounding with intent. He had previously pleaded guilty to being in possession of a knife.

Senior Investigating Officer, DI Sarah Totterdale said: “Following this awful incident in February, our officers quickly attended the scene at Milford Haven Comprehensive School along with other emergency services, and a lockdown was implemented.

“Shortly afterwards, we managed to trace and arrest the then 15-year-old boy, who was subsequently charged on February 7.

“The victim in this case has shown immense bravery, and to re-live the events of that day during the trial must have been incredibly traumatic. We are thankful for her assistance in this investigation, and hope that in time she can obtain closure from this ordeal.

“We are also grateful to teachers and students of Milford Haven Comprehensive School and the local community, who will also have greatly felt the impact of this incident. Finally, thank you to our emergency service partners and Pembrokeshire County Council for their assistance, and members of the wider community for their support.”
