Newtown High School has issued a statement after the school went into a "short and full" lockdown on Monday afternoon (June 14).

Headteacher Rob Edwards said: "We take all threats seriously and regret that people who make false threats on social media do so without concern for the upset, anxiety and disruption caused".

Dyfed Powys Police said it is investigating the source of a "threatening" social media message that was sent to a pupil.

In a letter to parents, Mr Edwards said: "The decisions of the school were informed by information provided by the police yesterday. At 3.40pm the police confirmed that it was safe for the lockdown to be lifted and we were able to release the pupils from the site in a safe and orderly manner, slightly later than usual.

"It is very difficult for the school to provide updates to parents on an ongoing police investigation and we would respectfully ask that parents remain calm and understand that we are prioritising the safety and wellbeing of pupils.

"When lockdown was lifted, we released a statement by 4.10pm, which was later followed by a statement from Dyfed-Powys Police

"Can I apologise for any inconvenience this may have caused but I am sure you appreciate the safety of all our pupils and staff is always our priority. We take all threats seriously and regret that people who make false threats on social media do so without concern for the upset, anxiety and disruption caused.

"We all have a duty, as responsible citizens, to use social media properly. As a school we will support the Police in any actions they take against anyone who commits such actions."

No-one was injured during the incident and all students were understood to be safe.
