LONDON - Britain's cities were largely quiet Thursday after days of rioting and looting that drew thousands of extra police officers onto the streets and a stern warning from Prime Minister David Cameron that order would be restored by whatever means necessary.
Tensions remained high even in the absence of any major incidents, and Cameron has recalled Parliament from its summer recess for an emergency debate on the riots later Thursday. He will face mounting pressure to reconsider planned police budget cuts, which critics claim will strain an already overstretched force.
An eerie calm prevailed over most of London overnight, with a highly visible police presence watching over the capital. Metropolitan Police said objects had been thrown at officers in south London's Eltham neighborhood but that the incident had been "dealt with" and a group was dispersed.
The incident reportedly occurred when a group of people who had gathered to defend their neighborhood against any potential looting were forced by police to clear the streets.
Other cities where looters had wreaked havoc earlier this week also came through the night largely unscathed, though for the first time minor disturbances were reported in Wales.
Police continued to make arrests linked to the disturbances, with the number of arrests in London alone climbing to 820. Courts were kept open around the clock to process alleged looters, vandals and thieves including one as young as 11.CBS News correspondent Mark Phillips reports police have published dozens of images from CCTV cameras showing the faces of suspects from the riots. Police forces say they're getting warrants and raiding houses, searching for stolen goods - and the people who took them.
Even as Cameron promised Wednesday not to let a "culture of fear" take hold, tensions flared in Birmingham, where a murder probe was opened after three men were killed in a hit-and-run incident as they took to the streets to defend shops from looting.
"We needed a fightback and a fightback is under way," Cameron said in a somber televised statement outside his Downing Street office after a meeting of the nation's crisis committee. As if to indicate his resolve, he underlined "nothing is off the table" including water cannon, commonly used in Northern Ireland but never deployed in Britain.
Outside the capital, in England's second largest city of Birmingham, police launched a murder investigation into the deaths of the three men hit by a car. Residents said the victims, aged 21 to 31, were members of Birmingham's South Asian communities who had been patrolling their neighborhood to keep it safe from looters.
"They lost their lives for other people, doing the job of the police," said witness Mohammed Shakiel, 34. "They weren't standing outside a mosque, a temple, a synagogue or a church they were standing outside shops where everybody goes. They were protecting the community."
Tariq Jahan, whose 21-year-old son Haroon was killed, stood in a Birmingham street and pleaded with the South Asian community not to seek revenge against the car's occupants, reported to be black.
"Today we stand here to plead with all the youth to remain calm, for our community to stand united," he said. "This is not a race issue. The family has received messages of sympathy and support from all parts of the community all races, all faiths and backgrounds."
He remonstrated with angry young men, urging them to "grow up" and go home.
Chris Sims, chief constable of West Midlands Police, said a man had been arrested on suspicion of murder.
"The information we have at the moment would support the idea that the car was deliberately driven," he said, appealing for calm. "My concern would be that that single incident doesn't lead to a much wider level of distress and even violence between different communities."
The violence has revived debate about the Conservative-led government's austerity measures, which will slash 80 billion pounds ($130 billion) from public spending by 2015 to reduce the country's swollen budget deficit.
Cameron's government has slashed police budgets as part of the cuts. A report last month said the cuts will mean 16,000 fewer police officers by 2015.
London Mayor Boris Johnson like Cameron, a Conservative broke with the government to say such cuts are wrong.
"That case was always pretty frail and it has been substantially weakened," he told BBC radio. "This is not a time to think about making substantial cuts in police numbers."
Scenes of ransacked stores, torched cars and blackened buildings have frightened and outraged Britons just a year before their country is to host next summer's Olympic Games, bringing demands for a tougher response from law enforcement. Police across the country have made almost 1,200 arrests including the more than 800 in London since the violence broke out in the capital on Saturday.
Britain's soccer authorities were talking with police Wednesday to see whether this weekend's season-opening matches of the Premier League could still go ahead in London. A Wednesday match between England and the Netherlands at London's Wembley stadium was canceled.
Britain's riots began Saturday when an initially peaceful protest over a police shooting in London's Tottenham neighborhood turned violent. That clash has morphed into general lawlessness in London and several other cities that police have struggled to halt.
While the rioters have run off with goods every teen wants new sneakers, bikes, electronics and leather goods they also have torched stores apparently just to see something burn. They were left virtually unchallenged in several neighborhoods, and when police did arrive they often were able to flee quickly and regroup.
Some residents stood guard to protect their neighborhoods Sikhs protected their temple in Southall, west London, and some 1,000 far-right members reportedly took to the streets to deter rioters.
