Patrol cars, a double-decker bus and shops were set alight after a crowd of more than 300 people clashed with officers near Tottenham police station.
Missiles, including Molotov cocktails, fireworks, rocks and fire extinguishers, were thrown at the police. Scotland Yard said at least one of the officers had suffered head injuries.
Trouble flared after members of the community took to the streets on Saturday night to demand “justice”, after Mark Duggan, 29, was shot dead on Thursday.
After sections of Tottenham High Road were cleared of protesters, “pockets of trouble” continue to flare in nearby areas, a Scotland Yard spokesman said.
Two vans were reported to have been set ablaze in nearby Rheola Close, and Sky News said that its reporter and cameraman had to withdraw from the area over safety fears.
There were also reports of looting in Tottenham Hale Retail Park.
A spokeswoman for London Ambulance Service said paramedics had treated 10 people, and nine were taken to hospital.
The violence erupted after around 120 people marched from the local Broadwater Farm area to Tottenham police station on Saturday, forcing officers to close the High Road and put traffic diversions in place.
After night fell, two police cars parked about 200 yards from the police station were set upon.
Scotland Yard said in a statement: “Two police cars had parked up at Forster Road/ High Road while their officers conducted traffic patrols on foot. This is about 200 yards north of Tottenham Police Station.
“At approximately 8.20pm a number of bottles were thrown at these two cars. One was set alight and the second was pushed into the middle of the High Road. It was subsequently set alight.
“The officers were not in the vehicles and were unhurt.
“Officers from the Territorial Support Group have been deployed to disperse the crowd. They are deployed to the north and south of Tottenham Police Station in the High Road, and are subject to bottles and other missiles being thrown at them by the crowd.”
A family friend of Mr Duggan, who gave her name only as Nikki, 53, said the man’s friends and relatives had organised the protest because “something has to be done” and the marchers wanted “justice for the family.”
……”They’re making their presence known because people are not happy,” she added. “This guy was not violent. Yes, he was involved in things but he was not an aggressive person. He had never hurt anyone.”
Hey Nikki, what about justice for all the lives and businesses destroyed by the rioting punks? “He was involved in things….” Yeah, I bet the cops shot him on the way home from a Bible study class.
Duggan, 29, was shot by officers from the Metropolitan Police’s CO19 unit on Thursday evening after the minicab he was travelling in was stopped. There was an apparent ‘exchange’ of fire and a bullet was found lodged in a police radio.
Duggan died at the scene and an officer was injured, but left hospital after treatment.
Here’s the rioting thugs:
