5.29pm: My colleague Vikram Dodd writes about the Independent Police Complaints Commission's initial ballistics results on the shooting of Mark Duggan, which triggered Saturday's initial riots in Tottenham.
The results show:
The bullet lodged in the police radio is a "jacketed round". This is a police issue bullet and, while it is still subject to DNA analysis, it is consistent with having been fired from a Metropolitan police Heckler and Koch MP5 submachine gun.
The firearm found at the scene was a converted BBM "Bruni" self-loading pistol. This is not a replica; the scientist considers it to be a firearm for the purposes of the Firearms Act and a prohibited weapon and is therefore illegal.
The handgun was found to have a "bulleted cartridge" in the magazine, which is being subject to further tests.
At this stage there is no evidence that the handgun found at the scene was fired during the incident. The FSS has told the IPCC that it may not be possible to say for certain; however further tests are being carried out in an attempt to establish this.
