Video has emerged showing the moment armed police confronted two men suspected of murdering soldier Lee Rigby in Woolwich.
The dramatic footage obtained by the Daily Mirror shows suspect Michael Adebolago (28) running towards officers as a second man, named locally as 22-year-old Michael Oluwatobi Adebowale, runs alongside, aiming his gun at the officers.
The video shows Adebolago being sent to the ground by two shots from the police car, before two officers jump out to cover him.
The officers arresting Adebolago do not appear to see Adebowale aiming his weapon at them but a third office spots him and he is brought to the ground as a further six shots are fired.

In other developments today, two new arrests were made: a man and a woman on suspicion of conspiracy to murder, following raids at six addresses in London and Lincoln.
It also emerged that the two suspected killers of Drummer Rigby were already known to MI5 and, almost certainly, to counter-terrorism officers in the police. One of the men was stopped from travelling to Somalia to join the Islamist militia Al-Shabaab last year.
Security officials insisted that there had been no evidence that either of the two men were planning an imminent attack. Nor was there any evidence, they say, that they were discussing beheading. They point out that there were plenty of references to it in Islamist websites.
