LONDON - Rioters throwing petrol bombs battled police in a economically deprived district of London overnight, setting patrol cars, buildings and a double-decker bus on fire in some of the worst disorder seen in the British capital for recent years.

About 200 people rained missiles and bottles on riot officers near Tottenham district police station after a street protest over the fatal shooting of a man by armed officers earlier in the week turned violent.

Mounted police and riot officers on foot in turn charged the crowd to push them back.

Eight officers were taken to hospital, one with head injuries, as rioters smashed windows and looted buildings including banks, shops and a supermarket and torched three police cars in the main road near the local police station.

The trouble broke out on Saturday night following a peaceful demonstration over the shooting of Mark Duggan, 29, who was killed after an exchange of gunfire with police on Thursday.

Duggan had been in a taxi when it was stopped by armed officers as part of a pre-planned operation. One policeman escaped unhurt after a bullet struck his radio. Duggan's death is being investigated by the independent police watchdog.

Although there have been riots in other European countries linked to austerity measures to tackle large national debts, London police and local community leaders said anger at Duggan's shooting was the cause of the riot.

Tottenham has a large number of ethnic minorities and includes areas with the highest unemployment rates in London. It also has a history of racial tension with local young people, especially blacks, resenting police behaviour including the use of stop and search powers.

NOTORIOUS RACE RIOT IN 1985

The disorder was very close to where one of Britain's most notorious race riots occurred just over 25 years ago.

In 1985, police officer Keith Blakelock was hacked to death on the deprived Broadwater Farm housing estate during rioting in which around 500 mainly black youths rampaged through the streets, assauting police, looting and setting fires.

Classford Stirling, a youth worker from Broadwater Farm, said there had been growing anger recently over stop and search practices by police. "It wasn't just black kids. It was the youth in general who are frustrated at the way the police are treating them," he told BBC TV.

"Everybody's now thinking of the way Mr Duggan was shot and they want answers. It's very difficult to turn round and say to them this is the wrong way because they believe this is the only way that they're going to get attention."

Television pictures showed a blazing bus surrounded by rioters and hooded youths pelting an abandoned police car with rocks and missiles. Media reported some locals had to flee their homes to escape the violence.

While the bulk of the disturbance had been brought under control early on Sunday, pockets of trouble were still erupting nearby. Buildings were smouldering with plumes of smoke billowing across the skyline.

"The rioting in Tottenham last night was utterly unacceptable," a spokesman for Prime Minister David Cameron said. "There is no justification for the aggression the police and the public faced, or for the damage to property."

Police Commander Stephen Watson said the scenes were "very distressing" for Londoners and perpetrators would be brought to justice. "Our intention ... is to bring things to as swift a conclusion as we can. Our absolute aim is to restore normality."

Local member of parliament David Lammy said: "The Tottenham community and Mark Duggan's family and friends need to understand what happened on Thursday evening when Mark lost his life. To understand those facts, we must have calm."

London also saw riots at the end of last year when protests against government plans to raise tuition fees for university students in the centre of London turned violent with police and government buildings attacked.

During the most serious disturbances last December, rioters targeted the limousine belonging to heir-to-the-throne Prince Charles and his wife Camilla, kicking its doors, cracking a window and reportedly jabbing Camilla with a stick.
