The investigation into the death of Mark Duggan has found no forensic evidence that he was carrying a gun when he was shot dead by police on 4 August, the Guardian has learned.

A gun collected by Duggan earlier in the day was recovered 10 to 14 feet away, on the other side of a low fence from his body. He was killed outside the vehicle he was travelling in, after a police marksman fired twice.

The new details raise questions about the official version of events. The shooting triggered some of the worst riots in modern British history, which began in Tottenham, north London, in response to the treatment of the Duggan family. The investigation into Duggan’s death is being carried out by the Independent Police Complaints Commission, but the Guardian has learned new details of the shooting, and a much more complex picture than first revealed is emerging.’
