The boy cannot be named for legal reasons
A high school ‘star pupil’ has been sentenced to youth detention after stabbing a pupil in the back, a court heard.
The 15 year old, who cannot be named, knifed his teen victim in an apparent revenge attack after believing he had been speaking badly about him.
He is said to have lurked near the shops in Brookfield, Preston, in waiting for his victim and was seen circling the area on his bike.
When he saw the other boy approaching with a friend, he ran up behind them and lunged at his victim with a knife before telling him: “You’ve just been chopped”, Lancs Live reports.
Prosecutor Francis McEntee said the attack, which happened at 7:21pm on March 17, 2026, was premeditated and motivated by revenge. He played CCTV footage, taken from outside a house on Ingleton Road, which showed the attacker running up behind the unsuspecting schoolboy.
The youngster thought he had been punched and walked away from the attack but when he arrived home, a short distance away, he realised he had blood coming from his head.
He was taken to Royal Preston Hospital by ambulance where he was treated for knife wounds to his torso, the back of his neck and a defensive wound to his hand.
Michael Lavery, defending, said the boy had received glowing school reports and was considered to be academically high-achieving. However, he had adverse experiences in his childhood and was suspected of having autism.
These contributed to a heightened threat response, poor emotional awareness and emotional detachment, a psychological report said.
Sentencing, Judge Philip Parry said the teenager’s parents had worked with the authorities and sought support with their son. He said the teenager’s psychological profile helped to explain why ‘an intelligent boy could behave in such a catastrophic way.’
He said: “You told the author of the pre-sentence report that there was an issue between you and the other boy which you interpreted to be him being out to get you. You took a knife out in case he had one and was going to hurt you.
“I see no evidence at all of him threatening to hurt you or carrying a knife. There is no justification for you to take that knife from home and go in search of him, then waiting to find him and attacking him from behind.
“You offer no apology to your victim. Your only regret is you wish you had attacked him with just your fists, not with a knife.”
The judge said it was ‘concerning’ that the attack took place after intervention from the Youth Justice team after the teenager was cautioned for being involved with class A drug supply at a previous time.
“That intervention was unable to prevent serious future offending by you”, he said.
The court heard the youngster was initially charged with attempted murder, however he pleaded guilty to an alternative charge of section 18 wounding, along with possession of a bladed article.
Judge Parry said he must pass sentence based on the sentencing guidelines for young people, which prioritise rehabilitation and preventing future offending. However he said the offence was so serious it could only be met with an order for youth detention.
He said: “This was very serious offending indeed. There is too much knife crime on our streets. Young men and boys lose their lives frequently in knife attacks similar to this one.
“It is as depressing as it is terrifying.”
The victim said he now feels on edge and on high alert as a result of the attack. He is receiving counselling in an attempt to move forwards, he said.
Judge Parry handed down a two-year detention and training order meaning the 15-year-old will spend a year in custody and a year under supervision in the community.
