Amman Valley School, or Ysgol Dyffryn Aman, is a bilingual comprehensive school for those aged between 11 and 18.
It is maintained by Carmarthenshire County Council and provides education to 1,450 school pupils and 270 sixth form pupils.
In an interview with WalesOnline, Cllr Karen Davies – a LEA governor at the school – said she had been told the incident involved a stabbing.
Cllr Davies said she did not know whether any children had been injured.
“I have been told someone has been arrested and that two members of staff have been stabbed, but have no confirmation on how serious the injuries are,” she told WalesOnline.
“I send my thoughts to those injured and all the people there. I know how well the school rehearsed lockdown and I am sure everything is under control.
“It is shocking. You hear about these things happening in Manchester and London but it is literally our comprehensive here.”
