There is no evidence Mark Duggan opened fire at police before being shot dead by officers, the Independent Police Complaints Commission has said.
Mr Duggan, 29, whose death sparked the first riots in Tottenham, 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 there was "no evidence that the handgun found at the scene was fired".
An inquest heard the father of four died from a single bullet wound.
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.
