London Burning: Video Aftermath of Looting, Riots

Violent rioting Saturday night left 26 London police officers injured, after a peaceful protest over a fatal officer-involved shooting devolved into a fiery rampage.

Businesses, police cars and a double-decker bus were torched as between 300 and 500 people descended upon north London's Tottenham area, looting and clashing with officers while demanding "justice" for Mark Duggan. Police said 46 were arrested, according to the Associated Press.

Duggan's family condemned the rioting. Police sources last week described Duggan, a father of four, as a "gangster," something his brother Shaun Hall strongly denied.

"There should be someone here putting our minds at rest about what happened," Hall told London's Sky News. "He's not some type of gangster. He's a family man."

British media said that an officer involved in the shooting had a bullet lodged in his radio, suggesting a gunfight, but other details were scarce. Hall said his sibling would never shoot at police.

"That's ridiculous," he told Sky.

As the rioting escalated Saturday, protestors lit up social networking sites, trying to spur others to join them.

Daily Mail:

One user calling himself ‘English Frank’ urged attacks on the police, saying: ‘Everyone up and roll to Tottenham f*** the 50 [police]. I hope 1 dead tonight.’

And in a clear incitement to looting, ‘Sonny Twag’ tweeted: ‘Want to roll Tottenham to loot. I do want a free TV. Who wudn’t.’

‘Mrs Lulu’ tweeted: ‘Brehs [men] asking who’s down to roll [go] Tottenham right now, to get justice. – RIP Mark x.’

A tweet apparently passed on by chart-topping rapper Chipmunk, who comes from Tottenham, paid tribute to the dead man: ‘R.I.P Mark Duggan a real straight up and down respected man. LOVE!!!!!!!!’

Joining in the Twitter frenzy, ‘Ashley AR’ tweeted: ‘I hear Tottenham’s going coco-bananas right now. Watch me roll.’

Prime Minister David Cameron strongly condemned the violence and on Sunday the Scotland Yard police commander Stephen Watson described it as "distressing."

"What we experienced earlier on yesterday evening was a peaceful protest outside Tottenham police station -- there was no indication it would deteriorate in this way. For those who involved themselves in this level of violence, there is no excuse," Watson said.
