• Police in Gloucestershire were called to the Tewkesbury Academy just after 09:00 BST
• A teenage boy allegedly stabbed a male teacher in a corridor
• The teacher was taken to the Gloucestershire Royal Hospital, where he is in a stable condition

• Pupils were locked down after the incident, but were allowed to leave later in the afternoon
• Police later revealed the suspect was arrested by firearms officers around 11:00 BST, around five miles from the school
• He is now in being held on suspicion of attempted murder

Here's a screengrab of the email sent to parents and carers at the Tewkesbury Academy this morning.

Ocone says the suspect, a teenage boy from Tewkesbury, was arrested on suspicion of attempted murder.

He remains in custody.

The motivation for the attack is still unclear, Ocone says - but he adds the incident was not terrorism-related.

Ocone says it was initially thought the suspect had fled the scene and was hiding in the school grounds.

The academy was locked down and neighbouring schools were also asked to lockdown.

Plain clothed officers were deployed in the wider area around the school.

The suspect was arrested by firearms officers at 11:00 BST - two hours after the initial call.

The arrest happened in Stoke Orchard - about five miles away, between Tewkesbury and Cheltenham.

Ocone says that police got two calls this morning - from the school and from the ambulance service - saying a male teacher had been stabbed in a corridor, and he suffered a single stab wound.

He is now in a stable condition, Ocone says.

We're now hearing from Gloucestershire Police Assistant Chief Constable Richard Ocone.

Year 7 pupil Katie Gardiner was collected from the school gates by her worried parents this afternoon.

"It was quite scary as we had never had anything like that before. My old primary school also got shut down," she tells PA news agency.

She says the teachers "did a really good job in keeping us calm and making sure we had fun".

Her mother says that once the school was locked down, teachers allowed students to switch on their mobile phones and message their families to say they were safe - although school rules normally state that phones are to be switched off.

"We are really relieved to see her. We know she has been safe for many, many hours but until you actually see them you don't know," Katie's mum Julia says.

"We couldn't ring but we were allowed to text, which was really reassuring.

"They had quite a lot of fun with sweets and doing a geography quiz and the teachers did a fantastic job keeping everyone calm."

We are expecting an update from police soon - once it starts, you will be able to watch it by pressing play at the top of the page.

A parent of a pupil at Tewkesbury School describes the suspected stabbing at the school as the "worst nightmare of anybody".

Rich, whose son is in year 8, says his wife received news of the attack via text message. The pair went to the school with another son, who recently completed his GSCEs.

He joined other parents gathering inside a nearby garden centre, where school representatives were sharing updates.

"The school, the police and the garden centre have been brilliant. In completely unprecedented circumstances, they have done an outstanding job," he tells the BBC.

"The poor teacher. You don't expect to be attacked doing your job - helping children. Our thoughts go out to him an his family."

He adds: "You don't expect this - this is Gloucestershire."

One pupil, Lily, tells the BBC that teachers didn't tell her class what had happened at first, other than the classroom doors were being locked.

"My mum had messaged me and I wasn't sure what was going on," she explains.

"I did get worried, but I did start to calm down because I was with my friends in the classroom."

She says pupils found out about the incident via the news, family and friends.

Lily says her teacher continued with the lesson and, once it ended, they stayed in the classroom playing games on their tablets and watched a film.

"We were all there for each other," she says.

Her mother, Carly, says she is "feeling better" now her daughter had been allowed to leave school. And she praises the school for how they responded to the suspected stabbing.

Geoff Barton, general secretary of the Association of School and College Leaders (ASCL), has commented on the suspected stabbing of a teacher at Tewkesbury Academy.

"While we are not aware of the details of what has happened, this is clearly an appalling incident and the teacher concerned and all affected are in our thoughts and prayers," he says.

The school has now confirmed that pupils are being allowed to leave, as we reported earlier.

"Parents should arrive at Dobbies Garden Centre from 1pm where the police will co-ordinate the parents of each year group arriving at the academy to ensure every child leaves safely and efficiently," the school statement reads.

"There will be additional buses to take pupils home earlier."

The statement adds: "If we do not receive your consent, children will be kept on site until 3.25pm."

Here's more on the teachers' response to the suspected stabbing this morning.

Erica Farley, the mother of a student at Tewkesbury Academy, tells the PA news agency she is "very concerned for her son".

But she also says she is "very happy in the knowledge that the staff at the school and the police have provided an incredible response in keeping our children safe and have brought this to a swift conclusion".

We have just heard from a parent of a Tewkesbury School pupil, who says a teacher barricaded the door of his daughter's classroom to keep the pupils safe.

The father says his daughter - a year 8 pupil - was in drama class when the the incident occurred.

He tells BBC reporters at the scene it was a "big scary affair" to be told of the alleged stabbing via text message.

The father says he then received a video call from his daughter while she was inside the classroom.

"She was so brave, she took it really well," he says. "They were all frightened and scared but my daughter has been absolutely fantastic."

He also praises the teachers' response.

“The teachers have been absolutely phenomenal – I’ve seen some video from my daughter and I can just see him [his daughter's teacher] he’s there supporting the whole class," he says.

Describing the footage, he says the teacher sat by the door and barricaded it by placing boxes in front of the entrance.

He then says the teacher draged a wardrobe across the room to also place in front of the door.

He kept "everyone cool - even though he must have been scared himself".

After being locked down since the stabbing at around 09:00 BST, some pupils are now being allowed to leave the school, our reporters at the scene say.

Reporting from Tewkesbury School

As we reported earlier, the school is still in lockdown after the stabbing, which happened at around 09:00 BST.

Now though pupils are being moved from the sports hall, where they had gathered, back to classrooms.

The prime minister's thoughts are with those impacted by suspected stabbing at a school in Tewkesbury, No 10 says.

Rishi Sunak's official spokesman said he expressed his sympathies with "the individual who has been injured and with the staff and pupils of the school who would obviously be extremely concerned".

Sunak also thanked police and emergency services "for their ongoing response," his spokesperson added.
