A 13-year-old boy who allegedly shot his teacher in the face with a pellet gun will be referred to a disciplinary panel, the chair of the school's governors has said.
Darren Jones, who is head of PE at Maesydderwen Comprehensive School in Ystradgynlais, south Wales, suffered a graze to his face after the incident.
The teenager was taken into custody after the incident at the 540-pupil school at around 9.30am on Wednesday, Dyfed Powys police said. The teenager is still in police custody, a force spokesman confirmed.
The teacher did not require hospital treatment.
Hugh Pattrick, 64, has been head of the governors for more than 10 years and said the incident came as a "huge shock" to the small community.
He said: "The matter will be considered by a school disciplinary panel and it is sad for the youngster because it will be a blot on his life.
"It is a very caring school with a very good pastoral system. It is a close-knit community and we pride ourselves on being a caring environment. This has been a huge shock."
Mr Pattrick said he did not know when Mr Jones would return to work.
He said: "He was very shocked so I do not know if he will be back today. It depends how long it takes him to recover from the shock."
He added: "The head handled the whole thing very well. She gathered all the children in the hall to tell them what had happened. A couple of children went home after their parents came to collect them but the school carried on as normal and will continue to do so."
