The teenager who killed pensioner Richard Mannington Bowes during the London riots can be named as Darrell Desuze after an order banning his identification was lifted at Inner London Crown Court.
The 17-year-old had been protected because of his age but a judge removed the order at Inner London Crown Court today a day after he admitted manslaughter.
Desuze, of Bath Road, Hounslow, punched Richard Mannington Bowes to the ground on 8 August last year during rioting in Ealing, west London. He knocked the man to the ground where he banged his head.
Mannington Bowes died on 11 August, three days after being attacked and suffering brain damage.
Desuze also pleaded guilty to violent disorder. He had previously admitted burglary at William Hill, Tesco Express, Blockbusters and Fatboys Thai restaurant on 8 August.
Mr Justice Saunders said in terms of consequences, it was the most serious crime committed during the riots and the public had a right to know what happened and who killed Mr Bowes, a retired accountant.
Desuze, who a year before the riots enjoyed a school trip to the Metropolitan Police's riot training centre in Gravesend where he watched a simulated riot with officers pelted with bricks, still faces a charge of murder but the Crown will not pursue it and it is expected to lie on file.
Brian Altman QC, prosecuting, said on the evening of the killing Desuze, known as Smokey, set off for Harrow with friends.
But they headed to Ealing after getting a text from someone anticipating trouble there.
Desuze, wearing sunglasses and a distinctive top saying "Robbers and Villains" was caught on camera kicking in the glass doors of a shopping centre before joining a mob that attacked heavily outnumbered police with missiles around Spring Bridge Road.
"But one thing distinguished him from the others," said Altman.
"He killed Richard Bowes, an entirely innocent local resident who had intervened to extinguish flames and prevent a fire in one of the bins."
The barrister said left-handed Desuze threw his full weight behind a punch to Mr Bowes's jaw, buckling his legs, knocking him unconscious and backwards where his head took the full force of impact on the road.
The police were "simply unable to reach Mr Bowes for some minutes because of the violence against them," said Mr Altman.
After walking off, Desuze returned to the victim and moved him onto the pavement.
"If it was concern for what he had done, it was short lived," said Altman. "Instead of calling an ambulance or summoning any of the policemen around he was in minutes rejoining the riot."
Bowes sustained "catastrophic brain injuries" and never regained consciousness.
Altman said Desuze, who was just 16 at the time, left the scene and within 10 minutes of delivering the fatal blow was breaking into a William Hill, Tesco Express, Blockbusters and a Thai restaurant.
As officers and members of the public battled to save Bowes, who was breathing but unresponsive and bleeding, thugs continued to shower them with debris, the court heard.
Altman said the prosecution accepted Desuze's guilty plea only on a "full facts" basis.
He would not accept it if Desuze continued with his "belatedly" offered explanation - he wanted to argue that he was provoked and was acting in self-defence.
Desuze's mother, Lavinia Desuze, 31, will stand trial on Monday accused of perverting the course of justice by destroying the clothes he wore on the night.
She appeared at court today and chose to stay in the dock with the killer after her case was adjourned.
Desuze will be sentenced next month after pre-sentencing reports have been completed.
