The yob who stabbed a teenager almost to death in an Isleworth park has been jailed for three years after his original sentence was ruled "unduly lenient".
The now 15-year-old, who can not be named because of his age, came within inches of stabbing another boy aged 15 to death in a frenzied attack, narrowly missing his spinal cord and kidneys.
The court heard that, had he not been pulled off his victim during the assault, he would have killed the schoolboy.
But in December last year at Isleworth Crown Court, the thug was given a three-year supervision and surveillance order – a sentence which the Lord Chief Justice Lord Judge, has now condemned as "severely unduly lenient".
The boy who is a member of Hounslow gang Street Politics, was identified only as C at London's Criminal Appeal Court on Friday and was given a three-year supervision and surveillance order – a sentence which the Lord Chief Justice, Lord Judge, has now condemned as "severely unduly lenient".
"C" had admitted wounding with intent to cause grievous bodily harm, having an offensive weapon and a separate offence of assault by beating, which took place just hours before the stabbing.
He has also admitted three counts of robbery and a further count of possessing an offensive weapon at an earlier court hearing, offences committed four days before the stabbing.
Lord Judge heard argument from lawyers representing the nation's top law officer – Attorney General Baroness Scotland QC – who urged the judge, sitting with Mr Justice Collins and Mr Justice Griffith Williams to increase the sentence.
"C's" most serious offences occurred on June 17, last year. He rowed with a teenager at a Young Offender's centre in Isleworth, head-butting him and waving a knife at him.
He left the centre, but soon came across the victim with a group of friends. An argument broke out between the pair, and the victim struggled with "C", who was holding a knife. "C" then stabbed him six times, causing him injuries all over his upper body.
Lord Judge said: "We have come to the conclusion that the sentence in this case was unduly lenient and severely so."
He said the offences were "far too serious for us not to pass a custodial sentence".
Last year the Chronicle reported how the victim had been forced to change school and address since the attack because of the fear he would be targeted again.
