England riots: Reaction to another night of disorder
A further night of riots across several major towns and cities in England has been condemned.
There were disturbances in areas including Greater Manchester, Liverpool, Nottingham and Birmingham, with shops being looted and set alight.
A murder inquiry is under way in Birmingham after three pedestrians who were trying to protect their property were run over and killed.
Meanwhile, Manchester Police said rioters brought shame to the streets.
It remained largely quiet in London where 16,000 police were deployed. Force chiefs have been ordered to cancel all police leave by the home secretary.
Theresa May said "maximising the police presence on the street must be a priority" in areas affected by riots.
David Cameron said water cannons were being made available.
The prime minister said: "Whatever resources the police need they will get, whatever tactics the police feel they need to employ, they will have legal backing to do so."
Greater Manchester was one of the worst affected areas on Tuesday night, with firebombs thrown at shops and looters stealing clothes, electrical items and alcohol.
Hundreds of rioters have brought "shame on the streets", Greater Manchester's assistant chief constable Garry Shewan said.
He added: "This has been senseless violence and senseless criminality of a scale I have never experienced in my career before.
"It is important that people know Manchester remains open for business."
Some 108 people were arrested in the city.
Labour leader Ed Miliband was heckled as he took a walk around some Manchester streets where many shops and businesses were damaged by rioters and looters.
He said the priority was restoring public order.
"Then we have got to look into the causes, why people are going around doing this and I think there are a complex number of causes," he said.
He thought it was "partly about parental responsibility, partly about gangs and some of that culture".
When the BBC asked two youths why they were rioting, one responded: "Why are you going to miss the opportunity to get free stuff that's worth, like, loads of money?"
But they said it was not just about that, adding it was in response to government cuts.
One added: "How many people have they arrested really, though, 10? I'm not really bothered. I'll keep doing this every day until I get caught."
He added that it would be his first offence "so I'm not really bothered".
There was looting in Birmingham city centre, Wolverhampton and West Bromwich on Tuesday night.
Police stations firebombed
Police said there were 109 arrests in the West Midlands.
One man was arrested and a vehicle recovered after three men were killed when they were hit by a car in Winson Green, Birmingham.
It is believed the men aged 31, 30 and 20 were protecting their neighbourhood at the time of the incident.
The father of one victim has paid tribute to his son.
Tariq Jahan said of son Haroon Jahan: "He was a very good lad, a good man starting at the beginning of his life."
Mr Jahan added: "He was trying to help his community and he has been killed."
In Nottingham, five police stations across the city and one in Canning Circus station was firebombed by a mob of about 40 men.
Shops, cars and pubs were also damaged in certain areas of the city and police made more than 90 arrests.
About 200 youths gathered in the Toxteth area of Liverpool throwing missiles and causing disorder and damage, Merseyside Police said.
A resident of south Liverpool said: "The people that are opposed to what is going on need to show that they are against it, in any little way they can, whether it is just cleaning up or just go out tonight and hold a silent protest.
"There's no need to upset anyone but we need to show them that we are angry and there is no need to do it."
There were also smaller disturbances in Leicester, Coventry, Northampton and Cambridge.
In Gloucester, police officers came under attack from youths throwing rocks and bottles in the city centre.
Community clean-ups have been organised at several cities across the country.
Government minister Michael Gove has praised the Met's response to the riots, saying bringing in an extra 10,000 officers helped to prevent further riots from taking place in London.
A 21-year-old man has been arrested on suspicion of setting fire to the House of Reeves furniture store in Croydon. The man was held on suspicion of arson with intent to endanger life, Scotland Yard said.
A 26-year-old man shot in his car in Croydon during Monday's rioting has died and a murder investigation has begun.
Violence began in Tottenham on Saturday after the fatal shooting by police of Mark Duggan.
His family released a statement which said they were "deeply distressed by the disorder affecting so many communities across the country".
Deputy Assistant Commissioner Stephen Kavanagh said the use of plastic bullets - never before fired to deal with riots in England - would be "considered carefully" in the event of further disorder.
But he added: "That does not mean we are scared of using any tactic."
The Met Police force has launched a dedicated webpage to show images of people wanted over the disturbances at Metropolitan Police Service - Disorder Suspects Wanted.
