An "initial visual search" inside a car in which a man was shot dead by police has failed to locate any weapons, the police watchdog has said.
Anthony Grainger, from Bolton, died of a single gunshot wound to the chest after the car he was in was stopped in the village of Culcheth, Cheshire, on Saturday evening in what police described as a "pre-planned operation".
Mr Grainger died after being shot in the chest by an armed police officer.
The Independent Police Complaints Commission (IPCC) deployed investigators to the scene and took over the investigation following the shooting at around 7.20pm. Initial evidence collected suggests two police firearms were discharged during the incident, the IPCC said. However, a full ballistic examination needs to be undertaken on the recovered police weapons to confirm this.
At this stage it is known that one round was discharged by an officer carrying a Heckler and Koch MP5 carbine and this passed through the car windscreen and struck Mr Grainger, 36, while he was sitting in the driver's seat of a red Audi car.
Two Hatton rounds were discharged into the car's tyres by an officer carrying a shotgun in order to disable the vehicle. A CS canister was also deployed by hand into the vehicle by one of the firearms team.
An IPCC spokesman said: "Due to the presence of CS residue in the car a full forensic examination has not yet been conducted to establish whether there are any weapons in the car. This will take place in a controlled environment in the next few days. An initial visual search inside the Audi, and a search of the immediate vicinity of the car, has not located any weapons."
Earlier, Nicholas Rheinberg, the coroner for Cheshire, formally opened the inquest into Mr Grainger's death at Warrington Coroner's Court and then adjourned it, pending the findings of the investigation.
The inquest heard that Mr Grainger was born in Salford and lived in Deane Church Lane, Bolton.
His occupation was given as "odd job man".
