The 14-year-old boy killed in a sword attack in London yesterday was a pupil at the same school attended by Nottingham stabbing victim Grace O'Malley-Kumar, Sky News understands.

The development comes after Metropolitan Police Commissioner Sir Mark Rowley said one of the officers injured in the rampage in Hainault nearly lost her hand while apprehending the suspect on Tuesday morning. The schoolboy who was killed was a student at Bancroft's private school in Woodford Green.

Grace O'Malley-Kumar - who was killed in a knife attack in Nottingham in June last year - was a former student at the school. The school's flag is flying at half mast today after the most recent tragedy.

Ms O'Malley-Kumar's parents offered support to the schoolboy's family this morning. The boy's mother works at Holy Family Catholic School, which said in a statement on its website on Tuesday: "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." Four other people were injured in the attack in northeast London, including the female police officer and another officer.

None of their injures are thought to be life-threatening. Police have said they don't think it was a targeted attack, or terror-related, and they were working to establish the circumstances of what took place.

Officers were initially called to the scene at 7am with footage showing police apprehending a sword-wielding suspect after he was tasered. Sir Mark has said officers were "on the ground in 12 minutes" and that "some of the first contacts led to officers being very severely injured".

He said the two officers who were hospitalised suffered "horrifically serious injuries". Speaking on LBC this morning, he added: "I was talking to the family and colleagues of the woman officer who has a really badly damaged arm, really seriously damaged, the surgeon spent many hours basically putting her arm back together." Asked about reports she nearly lost her hand in the attack, Sir Mark said they were "not a million miles away".

An inspector also suffered a serious hand injury during the police response, with Sir Mark adding: "I saw him before the operation, he was in good spirits... I think that's partly the morphine, to be honest." Sir Mark did not confirm whether the two officers in hospital were the ones seen tasering the attacker.

The Met chief added that the 36-year-old suspect was detained after 22 minutes. Dramatic footage has shown the moment he was tasered on a driveway before several officers with batons approached him after he hit the ground.

The words "suspect contained" are eventually heard as a female officer pulls the sword away from the attacker. Sir Mark said this morning: "People say officers run towards danger.

"What you've actually seen on some of the videos that are around social media and on news sites such as your own... you actually see what that really looks like.

You've got officers running towards someone who's waving a sword." Police have said the suspect crashed a van into a house near the Tube station in Hainault before stabbing a number of people. The man has not yet been interviewed as he remains in hospital due to the injuries he suffered in the crash.

Metropolitan Police Assistant Commissioner Louisa Rolfe said there has been speculation about the suspect's background, including police contact with him. She said that "despite urgent and extensive checks today, we have found no trace of a prior incident involving him so far, but we will of course continue to make those inquiries".

'I can't stop envisioning the boy's face' James Fernando, someone who lives close to where the rampage took place, said the suspect had asked one of his neighbours to "take the telephone from him to tell whoever was on the phone his location". Mr Fernando added: "Within two seconds after that she's realised something isn't right, started running and he's pulled a samurai sword from the back of his trousers." He saw the neighbour shout to warn a boy who was on his way to school - but the man attacked him.

"It's quite traumatising now. I can't stop envisioning the boy's face," Mr Fernando added.

Speaking about what he saw of the suspect, Mr Fernando said: "He was running around, still after the police officers came, with the sword in his hand looking for victims."
