Initial ballistics tests on the bullet that lodged in a police officer's radio when Mark Duggan died on Thursday night show it was a police issue bullet, the Guardian understands.
The Guardian's crime correspondent, Sandra Laville, reports:
The revelation will fuel the fury in Tottenham about the killing of Mark Duggan by armed officers.
It also undermines suggestions that there was an exchange of fire between Duggan and the police before he died.
The bullet which was found lodged in the radio of one of the officers at the scene is still undergoing forensic tests. But reliable sources have said the first ballistics examinations suggested it was a police issue bullet.
These are very distinct as the Metropolitan Police uses dum dum type hollowed out bullets designed not to pass through an object.
The early suggestion from the IPCC was that the Met officers had returned fire after someone in the minicab opened fire. But the result of the ballistics early test suggests both shots fired came from the police.
