Many are linking last night's events with the late cancellation of Hackney Carnival today. There are also rumours flying around Twitter of riots planned for Enfield and Edmonton.
There are fears of more violent scenes tonight in Tottenham, with many hoping the forecasted rain might put protesters off. Meanwhile, those living at the scene of last night's riots have spoken out against the destruction. Christian Macani, 22, said:
What does this achieve? They can't get away with this, can they? People really don't think. It's stupid, this. They've achieved absolutely nothing. It's a joke.
The Allied Carpets/Carpetright building was one of the biggest to be set ablaze last night. Harry Wallop questions whether protesters made it a specific target.
Shadow Home Office Minister Shabana Mahmood has called for calm in the community tonight:
This was appalling and unacceptable violence which put people's lives and safety at risk and must not be tolerated.
An independent investigation into the shooting of Mark Duggan had already begun last week, and that is the right way to respond.
Unfortunately a small minority of people bent on violence responded in an unacceptable way. Now further investigations will need to take place to bring those who attacked people and property to justice.
The Home Secretary must ensure the Metropolitan Police have the necessary support and resources to ensure calm is maintained tonight, while maintaining police priorities elsewhere.
And community leaders in Tottenham must be listened to. As David Lammy has said this morning, this violence does not represent the will of the community.
protest over the fatal shooting of a 29-year-old man by police on Thursday that started peacefully suddenly turned violent. Several buildings, cars and a double-decker bus were set on fire before order was restored.
The crowd numbering in the hundreds also broke shop windows and looted stores, pushing carts full of stolen goods down the streets of the Tottenham district of north London.
Police are now patrolling the district with concern of more trouble later on Sunday.
The rioting was the worst London has seen in years.
