A TEENAGER has been arrested following a firearms incident in a Welsh town where hours earlier two teachers and a student had been stabbed.

Dyfed-Powys Police said a warrant was executed at an address in Ammanford, Carmarthenshire, overnight and that officers had recovered a BB gun “following threats involving a firearm.”

The two teachers and a pupil who were hurt in a stabbing at Amman Valley School in Ammanford on Wednesday morning have been discharged from the hospital, police said.

One of the teachers injured in the attack has been named as Fiona Elias, the head of Year 7, and the second is reported to be special needs teacher Liz Hopkin.

The school went into lockdown after a “code red” alarm sounded through the PA system.

Teachers union NASUWT general secretary Dr Patrick Roach said: “Schools should be places of safety and sanctuary, and it will be of the utmost concern for every teacher whenever that sense of safety and security has been broken.

“No teacher should have to fear being assaulted at work, and everything that can be done must be done to ensure the safety of staff and pupils.”
