The council has confirmed that Ysgol Dyffryn Aman will be closed tomorrow (Thursday, April 25) to all pupils and staff in order for Dyfed Powys Police to carry out their investigation.

“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.

“I would also ask that people do not speculate while there is a police investigation ongoing.
