A 14-year-old girl who told police officers "I stabbed her - oopsies" after attacking two teachers and a pupil at a school has been detained for 15 years. The girl, who cannot be named for legal reasons, was earlier found guilty of attempting to murder , and a pupil, at Ysgol Dyffryn Aman in Ammanford, Carmarthenshire, in April last year.

The girl, who was 13 at the time, attacked Mrs Elias during the morning break using her father's multi-tool. Ms Hopkin stepped in to help, attempting to restrain the girl but was injured herself, receiving injuries to her neck, back and legs. Other members of staff stepped in and attempted to calm the teenager, and she ran off to stab another girl before being restrained.

All three victims survived the attack.

Ms Hopkin, who was stabbed in the neck, had to be flown by air ambulance to Cardiff.

The girl was found guilty of attempted murder at Swansea Crown Court following a week-long trial earlier this year.

She had previously pleaded guilty to three counts of wounding with intent and a further count of possession of a bladed article on a school premises - but denied attempted murder.

At Swansea Crown Court on Monday, Judge Paul Thomas KC sentenced her to 15 years' detention - of which half is to be spent on remand.

Sentencing the girl, the judge said he did not believe she had shown genuine remorse for her actions.

"I think you enjoyed the reaction and the publicity," he said.

"I don't think you are genuinely sorry for what you did; you have said you are, but I don't think that's how you really feel.

"You will have been told by those representing you that you will have to be kept in a secure place, as you have been for nearly a year already.

"Even there, where you are at the moment, you are a danger to others, and you have made threats to someone."

He said the attacks have caused "large number of people a great deal of people harm and upset".

The judge said he believed the girl intentionally carried out the attack during the school break, to have the biggest audience possible.

He said: "You wanted as many as possible to see what you planned to do," he said.

"What you thought of Mrs Elias, what you thought (the other pupil) might have done to you, whatever problems with bullying you had, none of that comes within a million miles of what you did or tried to do."

Witnesses heard the girl yell "I'm going to f****** kill you" and pull out a knife as she attacked the first teacher.

The jury also heard she had told friends she was going to "do something stupid that could get me expelled" which could involve Mrs Elias on the day of the attack.

Following her arrest, the girl made a number of unsolicited comments in the back of a police vehicle, telling officers, "I stabbed her - oopsies."

"I'm pretty sure this is going to be on the news, so more eyes will be looking at me," she said.

"That's one way to be a celebrity."

She also asked, "are they dead" and "how am I going to face my family after what I've done?"

In February, the judge said if she had been an adult the most likely outcome would have been a life sentence.
