A 13-year-old girl has been charged with attempted murder after a stabbing at a school in Wales.

Two teachers and a pupil were injured following the incident at Amman Valley School, also known as Ysgol Dyffryn Aman, in Carmarthenshire.

Superintendent Ross Evans, of Dyfed-Powys police said a teenage girl has been charged with three counts of attempted murder.

A 15-year-old boy was arrested on Wednesday and remains in custody after police received reports about messages on social media referring to the stabbing.

Dyfed-Powys Police said the teenage boy from the Cross Hands area was arrested on suspicion of making threats, which referenced the incident at Ysgol Dyffryn Aman.

The teachers, named as Fiona Elias, the head of Year 7, and reportedly special needs teacher, Liz Hopkin, have since been discharged from hospital along with the the pupil.

Superintendent Ross Evans said: “We would like to thank the many members of the public who reported concerns around messages they had seen online.

“This allowed us to take swift action in executing a warrant and arresting a suspect.

"While this investigation is being run separately to our inquiries into the major incident at Ysgol Dyffryn Amman yesterday, our officers will be seeking to establish both the credibility of the threats, and whether there was any connection between the alleged offences.

"Again, I would urge people not to speculate, not to share any images or videos relating to either investigation, and to allow us to carry out our enquiries fully.

"If you, or your children, are distressed by these events, please seek support from an appropriate agency."
