EXCLUSIVEYear 9 girl who 'tried to stab teacher to death with flick knife at Ammanford school has been in trouble in class before', says fellow pupil - as her 'protective' older brother is arrested after 'making threats with a BB gun'
A Year 9 girl accused of trying to stab a teacher to death 'has been in trouble in class before', a fellow pupil claimed to MailOnline today.
Yesterday, Ysgol Duffryn Aman secondary school went into lockdown after a schoolgirl allegedly 'went mad' with a knife in the playground, with three people treated for non-life threatening injuries.
The teenager, who is accused of stabbing another girl pupil before using the flick knife on two women teachers, was taken away in handcuffs after being arrested on suspicion of attempted murder.
Just hours after her arrest, her 'protective' older brother was also arrested for allegedly 'making threats with a BB gun'.
Today a fellow pupil at Ysgol Duffryn Aman secondary school has told MailOnline that the accused 'has been in a fair amount of trouble before'.

The 15-year-old boy, who spoke with his mother's permission, said: 'She was suspended. She has an older brother in school who has also been in trouble.'
The year nine pupil lives in Ammanford with her older brother, who friends said is very protective of her. It is unclear who the children reside with.
It is understood that her parents met while they were living on the south-coast. They are believed to have moved to South Wales before the suspect and her brother because the father's parents live in the area.
The couple are said to have split up after living at a number of different addresses. The girl's mother worked in a greetings card shop.
She described her daughter as a 'little minx' alongside a photograph of her in red lipstick and nail varnish.
The mother has now returned to the south coast and works in a food factory.
It is understood the girl's father started a relationship with a woman in the Ammanford area after they broke up. But that relationship also ended.
Officers swooped in to arrest the teenage girl's supposed brother at their family home in Ammanford, south-west Wales, overnight by the same police force investigating the knife attack at Ysgol Dyffryn Aman.
Dyfed-Powys Police declined to confirm the relationship between the two youngsters but locals in Ammanford, Carmarthenshire, confirmed they are brother and sister.
Supt Ross Evans, Carmarthenshire Commander today said: 'We would like to thank the many members of the public who reported concerns around messages they had seen online.

'This allowed us to take swift action in executing a warrant and arresting a suspect.
'While this investigation is being run separately to our inquiries into the major incident at Ysgol Dyffryn Amman yesterday, our officers will be seeking to establish both the credibility of the threats and whether there was any connection between the alleged offences.
'Again, I would urge people not to speculate, not to share any images or videos relating to either investigation, and to allow us to carry out our enquiries fully.
'If you, or your children, are distressed by these events, please seek support from an appropriate agency."
Locals remain on high alert after police raced to Ysgol Dyffryn Aman secondary school in Ammanford yesterday after a Year 9 pupil 'went mad' with a knife in the playground.
It is believed she stabbed another girl pupil before using the flick knife on two women teachers. She was taken away in handcuffs after being arrested on suspicion of attempted murder.
The two injured teachers have been named as Head of Year Seven Fiona Elias and special needs teacher Liz Hopkin. Rugby teacher Darrel Campbell stepped in to restrain the alleged assailant until police arrived.
Pupils hid in toilets and cupboards as the school went into lockdown for four hours and they have now been told to stay at home while police investigate the horrific attack.
The school's headteacher James Durbridge praised staff and pupils for their 'calm and mature' response.
On the school's website, Mr Durbridge said: 'Today has been a very difficult day. It goes without saying that my thoughts are with the three individuals and their families, who have been affected by today's incident.
'We are proud to have witnessed pupils embodying the school's core values while supporting their peers and staff.
'I wish to commend all staff and pupils for their calm and mature response during today's lockdown.'

He added that the school's 1,500 pupils could get 'wellbeing support' if they were affected by what they saw in the playground.
Armed with a flick knife, the teenager is said to have targeted the teacher, named locally as Liz Hopkin, before the head of year eleven Mr Campbell, a former rugby player, overpowered the girl and restrained her until police arrived.
A colleague then bravely stepped in to disarm the schoolgirl, forcing her to drop the weapon.
A schoolgirl witness said: 'Everyone was running and there were screams that the girl was going mad with a knife. Mr Campbell arrived on the scene and put her in an arm lock and got the knife off her.'
Mr Campbell 'does not think of himself as a hero', his brother said today.
Cefin Campbell, the Senedd member for Mid and West Wales, said: 'He's embarrassed by all the attention that he's had - he certainly doesn't consider himself a hero in any way.
'He just told me he just did what most people would have done - he acted instinctively, he saw the danger and took action.
'He really wants to play down anything more than just being a normal citizen, albeit a teacher in a school facing a very challenging situation."
Darrel Campbell, who has worked at the school for around 40 years, officially retired last year but was brought back on a part-time basis to help provide pastoral care.
Both he and his brother attended the school as pupils.
Cefin Campbell said he expected his brother would return to work when the school reopens.
He added: 'The school is closed today so he's off but he has every intention of going back whenever the school reopens.

'He wants to be there, with the other staff members, to support each other and to support the pupils that are under their care.
'He's taken that role very seriously throughout his life and he will go back to make sure that the pupils are in a good place.'
The politician said Darrel Campbell had been 'shaken by the whole experience as have all the staff, pupils, parents and so on'.
He went on to say: 'I think it's the sense of shock because he's been there for 40 years as teacher - he's never ever seen anything like this.
'I think that hits home to people that it should happen in a place like this.'
