The 14-year-old boy killed in the sword attack in north-east London attended the same school as one of the victims of the 2023 Nottingham attacks, the Guardian understands.

The teenager, understood to be Daniel Anjorin, was a student at the private Bancroft’s school in Woodford Green, which is still reeling from losing one of its alumni, Grace O’Malley-Kumar, who was stabbed to death in Nottingham in June 2023. The school is to issue a statement later on Wednesday.

A statement on the website of the Holy Family Catholic school, in Walthamstow, where the victim’s mother worked, said: “It is with great sadness that I share with you the news of the death of the child of one of our staff members.

“Mrs Anjorin’s son was taken from this life suddenly this morning on his way to school. Please keep Mrs Anjorin, her husband and their other children in your prayers.”

The man suspected of carrying out the stabbings in Hainault is to be questioned by detectives after doctors declared him fit to leave hospital and formally enter police custody.

The 36-year-old was arrested at the scene of a 22-minute violent rampage, first with a van and then a sword, that left the 14-year-old boy dead and four others injured.

The suspect sustained injuries after a vehicle crashed into a house in the north-east London suburb on Tuesday, before video showed him clutching a bladed weapon, and shouts of panic and terror as he moved around the area.

He was detained after being subdued by the firing of a Taser – an electric stun gun – but not before two police officers at the scene had sustained significant injuries.

Both were recovering in hospital, with a female officer having sustained serious limb injuries. Surgeons tried to save her arm and had to reattach nerves and blood vessels during an emergency operation.

The Metropolitan police commissioner, Sir Mark Rowley, hailed the bravery of his officers and gave further details of the trauma the two officers had suffered after coming face to face with the suspect.

Rowley told LBC radio: “I saw the [male] inspector whose hand is badly damaged. I saw him before the operation, and he was in good spirits. I think that was partly the morphine, to be honest.

“But he’s got a lot of patching up to be done on his hand. Really serious injuries there.

“And I was talking to the family and colleagues of the woman officer who’s really badly damaged [her] arm, really seriously damaged and the surgeon spent … many, many hours basically putting her arm back together. It will be a long journey of recovery.”

There was concern on Tuesday that the female officer had sustained injuries so severe she might lose her hand.

Rowley said: “It’s really horrifically serious injuries. I was in hospital three weeks ago with another officer who had been stabbed. I find going and seeing these young men and women – they are mostly in their 20s, they’re the same age as my kids, and they’re going out doing the most extraordinary things – I find it massively humbling that they are so connected to the mission of protecting the public. What they do is absolutely extraordinary.

“Based on what the surgeon was saying yesterday, we’re increasingly optimistic that with sort of months and years and lots of physio, that full recovery may be possible.

“Lots of repair work. It’s extraordinary what they do. So I think [the surgeon] spent hours and hours sort of operating under microscopes to reattach nerves and vessels and things. Just extraordinary.”

Rowley said the injuries showed the frequent dangers Met officers faced on the streets: “They’re just extraordinary. I find it humbling. They will run towards danger. But that’s not a glib phrase. That’s real.

“They are charging towards somebody with a sword. They’re putting themselves at risk because they are so connected to the idea of it’s their job to protect the public.

“And they do that day in and day out. Meanwhile, every day in London, on average, 19 officers are injured, 19 officers a day, seven days a week, 365 days a year. That’s the routine and, tragically, from time to time, some of those injuries are really serious like we saw yesterday.”

The Hainault incident has led to calls for the routine arming of police with guns.

Rowley said he did not support that and preferred the British model, in which police are largely unarmed with guns reserved for specially trained officers. He said a review was under way into whether more Met frontline officers should routinely patrol the streets with Tasers.
