A 13-year-old girl has been charged with three counts of attempted murder after two teachers and a pupil were stabbed at a school in south-west Wales.
Dyfed-Powys Police said the teenager was arrested at the scene at Ysgol Dyffryn Aman, in Ammanford, Carmarthenshire.
Two teachers and a teenage student were taken to hospital with non-life-threatening stab wounds.
They have all since been discharged.
The girl was also charged with possessing a sharp object on school premises and will appear before the Llanelli Magistrates Court on Friday, the Crown Prosecution Service said.
The school was closed for almost four hours at 11:20 GMT on Wednesday after teachers Fiona Elias and Liz Hopkin and a pupil tested positive.
Superintendent Ross Evans said: “A 13-year-old girl was arrested at the scene. I can confirm she has now been charged with three counts of attempted murder.”
“Subsequently, yesterday evening, our control room received a number of calls reporting concerns about messages shared on social media containing references to the incident here at Ysgol Dyffryn Aman.
“Officers quickly executed a search warrant at the home of the person believed to be responsible for this content.”
A 15-year-old boy has been arrested and is in custody.
Supt Evans said investigations were being conducted separately but officers were looking to see if the alleged crimes were linked.
“I would urge people not to speculate or share photos or videos of either investigation,” he said.
He thanked other emergency services, the NHS and others who helped after the incident.
Teachers and staff are expected to return on Friday to prepare the building for the return of pupils on Monday.
Vaughan Gething, the First Minister of Wales, said on Wednesday that he was “shocked” to hear what had happened.
“It is a very worrying time for the school, the families and the community,” he said.
“I want to thank the police and emergency services for their continued response and my thoughts are with everyone affected,” UK Prime Minister Rishi Sunak wrote on X, formerly known as Twitter.
Headteacher James Durbridge praised staff and students for their “calm and mature response” to the lockdown, saying it had been a “difficult day”.
