This is the face of the 16-year-old locked up for stabbing a man repeatedly with a 6in kitchen knife.

Pierre Lewis, who was convicted of attempted robbery when he was 13, knifed Ihab Chedade, 29, four times after a fight broke at the Edgar Road estate on the Hounslow borders, on June 30.

A row broke out after Lewis’ girlfriend threw a box of takeaway chicken out of the window, landing near where Mr Chedade was standing.

The pair began arguing before Lewis went downstairs to confront Mr Chedade, grabbing the serrated knife and hiding it down his trousers as he left his flat.

Witnesses reported seeing the two men arguing before Mr Chedade, believing the matter was over, walked towards his car along Simpson Road.

But the court heard Mr Chedade felt a blow to his left shoulder and realised he had been stabbed. As he turned away Lewis struck again, stabbing him in his chest and arm.

Prosecuting, Peter Clement, said: “Eyewitnesses saw the defendant pursue and stab Mr Chedade when he was on the ground.”

Lewis was seen fleeing the scene while Mr Chedade staggered to a nearby bus stop in Hanworth Road where passersby called the emergency services.

Mr Chedade was taken to West Middlesex Hospital but, because of the seriousness of his injuries, he was transferred by helicopter to St Mary’s Hospital in Paddington. He was treated for four stab wounds, a fractured wrist and an almost collapsed left lung.

Lewis, of Slade House, Edgar Road, Whitton, was arrested on July 31 and admitted wounding with intent to cause grievous bodily harm last month.

In mitigation, Nigel Mitchell read a letter stating his remorse written by Lewis to the judge. It said: “I think about what I’ve done every day.

“I’m not proud of it, it was a stupid mistake that will never happen again.”

Judge Tim Pontius lifted reporting restrictions to allow Lewis, who has five previous convictions, to be named because he said the matter of a teenager using a knife was of public concern.

As he jailed Lewis for eight years at the Old Bailey last Friday, Judge Pontius said: "You went looking for trouble and took a knife intending to use it.

“The fact is there is no doubt you intended to hurt him very badly. In that intention you were successful.”

Speaking after the hearing, Detective Constable Andy Thrower of Twickenham Crime Squad, who was in charge of the case, said he was happy with the sentence, which had been a result of five months hard work by his team.
