Following the Wednesday morning stabbings of two teachers and a student at a secondary school in south-west Wales, an adolescent girl has been placed under arrest on suspicion of attempting to kill.

Dyfed-Powys Police confirmed that the three victims are currently being treated in hospital for stab wounds following the incident at Amman Valley School in Carmarthenshire. 

Their injuries are not believed to be life-threatening and a knife has been recovered form the scene, the force said. 

Teachers placed the school into lockdown as dozens of police cars and helicopters arrived at the scene. 

Superintendent Ross Evans, Carmarthenshire Commander, said: “A teenage girl has been arrested on suspicion of attempted murder and currently remains in police custody.

“I would like to reassure parents and the public that the incident has concluded, and pupils have now left the school.

“We are working with the school and other agencies to ensure appropriate support is available to all involved.

“This was a very distressing incident and our thoughts are with the victims, their family and everyone impacted by what has happened.

“I am aware that there is footage of the incident currently circulating on social media and would ask that this is removed to avoid contempt of court and distress to those affected.”
