The investigation into Mark Duggan's death has found no forensic evidence to prove that he held a gun when he was shot dead by police on Aug. 4, it has been reported.

According to the Guardian, a gun collected by Duggan, 29, earlier in the day was found 10-14 feet away, on the other side of a low fence from his body.

The new revelations contradict the official version of the events that eventually led to widespread riots. An investigation into Duggan's death was launched by the Independent Police Complaints Commission (IPCC), but a much broader picture is now emerging following the latest revelations.

A video footage of the day of the shooting suggested that Duggan was carrying a gun. But detectives are now probing whether Duggan really held a gun when he was shot by the police.

The new details also cast a shadow on the Scotland Yard about the intelligence they had and its interpretation, the planning of the operation, tactics deployed, and also the actions of its firearms officers. The Crown Prosecution Service is likely to consider whether any officer should face criminal charge over the incident, the newspaper has said.

The exposé also questions the IPCC which came up with a different version of the shooting initially. The agency had to amend its initial statement, which originally came from the Scotland Yard, claiming that Duggan had fired the gun and that a bullet had lodged in a radio worn by a police officer. The IPCC later admitted that the bullet was probably a ricochet from the gun fired by a police officer.
