Police clashed with youths in Enfield as violence spread across London
Home Secretary Theresa May is to return from her summer holiday following a second night of violence in London.
More than 100 people have so far been arrested and 35 officers injured. Police vehicles were damaged and shops looted in parts of the capital.
Following riots in Tottenham on Saturday, disorder spread to Enfield in the north, Walthamstow in east London and Brixton in the south of the city.
Deputy Prime Minister Nick Clegg called the rioting "opportunistic theft".
Mrs May, who has been in contact with other senior politicians and senior police officers while overseas, is meeting Acting Metropolitan Police (Met)Commissioner Tim Godwin and other officers on Monday afternoon.
A Home Office spokesman could not confirm whether Mrs May has cut short her holiday to come back to the UK, or whether she was already due to return on Monday.
Earlier the home secretary said: "Last night, police officers again put themselves in harm's way to protect Londoners and their property.
"Londoners have made clear that there are no excuses for violence, and I call on all members of local communities to work constructively with the police to help them bring these criminals to justice."
A spokesman for Prime Minister David Cameron, who is on holiday in Italy, said: "We are very clear that those responsible for that violence and looting will be made to face the consequences for their actions."
'Copycat criminals'
On Sunday night, three officers were hurt when a vehicle hit them as they tried to make an arrest in Chingford Mount, north London.
Clashes later broke out in Enfield where shop windows were smashed and a police car damaged.

Up to 200 youths looted shops and charged police in Coldharbour Lane and the High Street in Brixton.
The disorder followed rioting in Tottenham which began on Saturday night and continued into Sunday morning.
A peaceful protest over the fatal shooting by police on Thursday of 29-year-old Mark Duggan was followed by violence later in the evening.
The unrest spread into nearby Wood Green and Tottenham Hale.
Deputy Prime Minister Nick Clegg described the second night of rioting as "needless opportunistic theft and violence" which he said had "absolutely nothing to do with the death of Mark Duggan".
The Met said it had dealt with several incidents of "copycat criminal activity" across London on Sunday night:
These included:
- Three officers injured after being hit by a vehicle in Chingford Mount, Waltham Forest, at about 00:45 BST
- More than 30 youths vandalising and looting a number of shops in Walthamstow
- About 50 youths gathered in Oxford Circus, central London, and threw objects at shops
- A police vehicle being attacked in Islington, north London
- A shop on the King's Road in Chelsea damaged
- A Tesco store in Ponders End being attacked and items stolen
Nick Clegg: "People indulging in violence, looting and theft have absolutely no excuse."
Metropolitan Police Commander Adrian Hanstock said: "This is not groups of people acting on behalf of communities or with any consent.
"This is individuals who are actually attacking communities, businesses, properties and houses and actually causing a huge amount of upset and criminality."
Kit Malthouse, Deputy Mayor of London and Chair of the Metropolitan Police Authority, described the scenes of the last two nights as "disgusting and shocking" and said the police did a good job.
He added: "Obviously there are people in this city, sadly, who are intent on violence, who are looking for the opportunity to steal and set fire to buildings and create a sense of mayhem, whether they're anarchists or part of organised gangs or just feral youth, frankly, who fancy a new pair of trainers."
Talking about the impact on the capital's image, one year ahead of the Olympic Games, he said: "It's pretty rotten for London, it does not look good.
"What we need to do over the next few months is to underline to people the fundamental truth about London which is that it is one of the safest, great big cities on earth."
He said the Mayor Boris Johnson, who is on holiday, was in touch with events and "all over this issue".
'Rocks and bottles'
BBC London's Paraic O'Brien said he had witnessed widespread looting in Brixton.
He said: "What really struck me was the small number of police officers that there actually seem to be on Brixton High Street responding to this."
Mark Duggan was shot dead by police in Tottenham
Deputy Assistant Commissioner Steve Kavanagh told the BBC Radio 4 Today programme there were too few officers in Tottenham on Saturday night.
But he said: "Social media and other methods have been used to organise these levels of greed and criminality."
Mr Kavanagh pledged that more officers would be on London's streets on Monday night to prevent or tackle further outbreaks.
Press Association photographer Lewis Whyld saw looters battle police at a Currys store in Brixton.
He said: "A couple of hundred youths were rioting and looting. Riot police went in to get them out and there was a big fight in the street.
"Youths were throwing rocks and bottles and there was a bin on fire. They used a fire extinguisher to push the police back so they could get back into Currys and continue taking things out."
Tube closed
Parts of Tottenham are still cordoned off, as officers and forensic specialists continue to examine Saturday's riot scene.
A total of 61 arrests have been made in connection with the first night of rioting.
The majority were for burglary, and other offences including violent disorder, robbery, theft and handling stolen goods.
Sixteen people have been charged with offences including burglary, violent disorder and possession of a pointed or bladed weapon following the Tottenham riots.
A police officer was also shot in Thursday's incident where Mr Duggan lost his life, which happened in what was called a "pre-planned" event under Operation Trident, which investigates gun crime in London's African and Caribbean communities.
Police had stopped a minicab which Mr Duggan had been travelling in.
An inquest into Mr Duggan's death is due to open at High Barnet Coroner's Court on Tuesday.
The violence has also affected public transport and the roads. This includes:
- Brixton London Underground station closed
- Tottenham High Road and Bruce Grove closed between Monument Way and the Roundway
- Lordship Lane shut between the A1010 High Road and Bruce Grove
- Church Street in Enfield closed between Chase Side and Willow Road
- Bus routes 67, 123, 141, 243, 259, 279, 349, 318, 341 and W4 are on diversion
