Detectives say the teenager has been charged with Section 18 Grievous Bodily Harm and possession of a bladed article on school premises. He has been remanded in custody and is due to appear before Swansea Magistrates Court today.
It comes after officers revealed that injuries initially described as “non‑stab injuries” have now been confirmed as stab wounds following detailed medical assessment.
‘Victim being supported after traumatic event’
Senior Investigating Officer DCI Matthew Briggs said the early description of the injuries was based on “preliminary information” available at the time, but specialist enquiries have since confirmed the wounds were caused by a blade.
He said the victim — understood to be a member of staff — is continuing to receive support as they recover from what police described as a “traumatic event”.
The school went into lockdown on Thursday after the incident, with pupils kept in classrooms while officers secured the site. Staff were praised for their calm and professional response.
Increased police presence to continue
Police say there will be a higher‑than‑usual presence around the school and surrounding area over the coming days to reassure pupils, parents and staff.
Officers will also be working with local secondary schools next week to offer support and guidance.
The school is expected to reopen as planned on Monday, with the headteacher previously telling parents that safety measures and wellbeing support will be in place.
A community still reeling
The incident has shocked Milford Haven, with parents describing the lockdown as “terrifying” and pupils reporting a heavy police presence around the site.
It follows two days of intense speculation online, which police have repeatedly urged the public not to fuel while the investigation continues.
This latest update confirms the most serious charge available for an assault of this nature, signalling the gravity of the incident and the scale of the ongoing investigation.
