A TEENAGER who damaged a man’s kidney with a knife and started an attack that put a younger boy in a coma for three weeks has been locked up.

York’s top judge told Callum Thomas Tooley to change his violent ways or face years in jail.

The stabbing in which Tooley injured Tyrone Savory in Clifton on February 27 was the latest in a series of violent outbursts.

The 17-year-old has been before the crown court for three separate crimes as well as the youth courts.

Eighteen months ago, aged 16, he started the attack on Knavesmire that left a 15-year-old in a medically induced coma for some days.

Under-18s cannot usually be named in court proceedings but The Press is able to name Tooley today after a judge lifted reporting restrictions at the newspaper’s request, on the grounds the public needed to know who he is.

The Recorder of York, Judge Stephen Ashurst, said Mr Savory was “extremely lucky” he had not been more seriously injured.

He told Tooley: “Unhappily, you have got a history of over-reacting violently in a number of different situations when you have lost your temper or you have been drinking or taking a substance. Sooner or later, someone is going to be really seriously hurt. If you carry on behaving in a violent way, then the courts will be left with no alternative but to lock you up for a long time indeed.”

The judge gave him a 20-month detention and training order. Because of his age, the maximum sentence for Tooley’s latest crimes was two years minus a discount for pleading guilty.

Tooley, of no fixed address, pleaded guilty to wounding and assaulting a woman who tried to intervene between him and Mr Savory.

He was on two youth rehabilitation orders at the time – one made on February 5 by Leeds Crown Court for injuring an officer when he needed restraining at Wetherby Young Offenders Institution, and one for criminal damage imposed by York Youth Court in December.

He was given a four-month detention and training order for the Knavesmire attack.

Alan Mitcheson, prosecuting, said on February 27, Tooley had been asked to leave a party in Clifton and refused to go. As others tried to throw him out, he seized a knife he saw in the hallway and recklessly waved it about.

Mr Savory suffered two stab wounds, one of which pierced his kidney. He was discharged from York Hospital after two days and has not returned for follow-up appointments.

For Tooley, Mark Partridge said the teenager was a vulnerable person who had not intended to harm Mr Savory and who would need help and assistance when he is released.

• Damien Dickinson, 20, of Lindsey Avenue, Acomb, received a 12-month sentence after admitting causing grievous bodily harm by breaking the 15-year-old boy’s skull in the attack on Knavesmire.
