Mark Duggan death: 'No evidence' Tottenham man opened fire
Mark Duggan was shot dead by police in Tottenham
There is no evidence Mark Duggan opened fire at police before being shot dead by a firearms officer, the Independent Police Complaints Commission has said.
Mr Duggan, 29, whose death sparked the first riots in Tottenham on Saturday, died from a single bullet wound to the chest, an inquest has been told.
He was shot in Ferry Lane, Tottenham, north London, on Thursday.
The police watchdog said ballistic tests showed "no evidence that the handgun found at the scene was fired".
Investigations by the IPCC show the father of four died after two shots were fired by a Scotland Yard CO19 firearms officer.
Forensic officers have told the IPCC it may not be possible to "say for certain" whether the handgun found near Mr Duggan was fired.
Further tests are being carried out to establish this.
After an inquest into Mr Duggan's death was opened and adjourned a statement from his family said they were "deeply distressed" by the disorder affecting communities across England.
Coroner Andrew Walker at the North London Coroner's Court in High Barnet adjourned the hearing until 12 December.
Search for truth
Mr Walker told members of Mr Duggan's family: "Can I just offer my deepest sympathies to the family of Mark Duggan.
"As members of the family will know, in due course there will be an inquest touching the death of Mark Duggan and this is the first stage in that process.
"Of course, as well as offering our deepest sympathies to members of the family, I would like to reassure members of the family that we will be working closely with the IPCC throughout the process."
Colin Sparrow, deputy senior investigator for the Independent Police Complaints Commission, which is looking into the shooting, told the hearing the inquiry could take up to six months.
Exchange of fire
A statement released by Mr Duggan's family read: "We want to establish the truth about Mark's death.
"The family want everyone to know that the disorder going on has nothing to do with finding out what happened to Mark.
"They also want everyone to know that they are deeply distressed by the disorder affecting so many communities across the country."
Mr Duggan's death occurred during an operation where specialist firearms officers were attempting to carry out an arrest.
The 29-year-old, a passenger in a minicab, was shot after an apparent exchange of fire with the officers from Operation Trident, the unit which deals with gun crime in the African and Caribbean communities.
A police officer's radio was later found to have a bullet lodged in it.
The IPCC immediately announced it would investigate the incident and later said it believed two shots had been fired by police.
It also confirmed an illegal firearm was recovered from the scene.
Metropolitan Police in Lewisham preparing for the riots. 
British Prime Minister David Cameron has stated that a change in police strategy is appropriate following what many feel to be an inadequate response to the rioting that has overrun many cities across England. Riots started in  on Saturday night after the fatal shooting by police of Mark Duggan, a 29-year-old taxi driver who the  state was in possession of a handgun, but did not fire it.

During the Parliamentary debate on the riots, , the Labour leader, called on Cameron to reconsider cuts to police budgets.   described the communities where the rioting occurred as being "left behind" and "cut-off from the economic life-blood of the rest of the country", and called for solutions to the "deep-seated social problems"

One avenue the Prime Minister is said to be considering is changing regulations on  services like Twitter, Facebook and , the latter being used to communicate between groups of rioters. The  and  came out in opposition to any plans to restrict communication using social media, with Jim Killock of the Open Rights Group warning that such regulation would be abused by the police and private companies.

In , England, three people were arrested by police for the suspicion of using Twitter or BlackBerry Messenger to encourage the rioting. The government is "working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these Web sites and services when we know they are plotting violence, disorder and criminality," said Cameron.

The Prime Minister also announced that he would consider using the  to support the police in controlling future rioting, and also that he would consult with , CBE, who had been the chief of police in Los Angeles and a police commissioner in New York City and Boston. Bratton is quoted as saying that arrests are not the only way to solve societal problems which lead to rioting and unrest: "You can't arrest your way out of the problem."
