Hundreds of people have gathered in Tottenham in North London to protest the death of Mark Duggan, a 29-year-old father of four..
A bus, a shop and two patrol cars were set on fire in Tottenham on Saturday night.
The protests began with a march from Broadwater Farm to a local police station.
Police apparently responded by closing roads.
Mark Duggan died on Thursday after what was claimed to be an exchange of fire with police.
The shooting has enraged many in Tottenham and community leaders have called for calm, undoubtedly mindful of the 1985 murder of police officer Keith Blakelock in the same area.
Suspected gangster Mark Duggan, 29, was travelling in a minicab at the time, allegedly fired a handgun at an armed cop, whose life was saved when the bullet hit his radio.
The officer returned fire hitting Duggan before slumping to the ground.
The British Independent Police Complaints Commission is investigating the incident.
Duggan, known by the street name Starrish Mark, was a so-called gangsta member of North London's Tottenham Man Dem gang, which has links to Jamaica's Yardies.
Cops from the Met Police Operation Trident, which tackles gun crime in London's black community, had him under surveillance amid fears he was about to avenge the killing of his rapper cousin Kevin Easton, 23.
Easton, who performed as Smegz, was stabbed to death in front a club in Mile End, East London, in March.
Three men aged 23 to 27 have been arrested for that murder.
