Duggan 'did not fire at officers'
The police shooting victim whose death sparked the riots did not fire at officers before he was killed, ballistic tests indicate.
There is "no evidence" that a handgun found at the scene where Mark Duggan was killed by armed officers was used, the Independent Police Complaints Commission (IPCC) said.
The 29-year-old's death, after receiving a gunshot wound to the chest last Thursday, was a trigger for the first night's rioting in Tottenham on Saturday.
Mr Duggan's death came after two shots were fired by a Scotland Yard CO19 firearms officer, investigations show.
The initial results confirmed reports that a bullet found lodged in a police radio at the scene was police issue.
Forensic officers have told the IPCC that it may not be possible to "say for certain" whether the handgun found near Mr Duggan was fired.
But an IPCC statement said: "At this stage there is no evidence that the handgun found at the scene was fired during the incident."
The IPCC said investigations into the circumstances of the shooting are continuing with a CCTV trawl of the area.
Mr Duggan was a passenger in a silver Toyota Estima people carrier minicab in Ferry Lane, close to Tottenham Hale Tube station, which was believed to have been stopped by police.
A non-police issue handgun, converted from a blank-firing pistol to one that shoots live rounds, was recovered close to the scene of Mr Duggan's death.
