SHOCKING video has emerged of the moment the two attackers lured police toward them by dragging their butchered victim into the middle of the road before they were shot at eight times.

The two men - identified as Michael Adebolajo, 28, and Michael Adebowale, 22 - can be seen brandishing weapons in broad daylight as they confronted officers following the brutal killing of Drummer Lee Rigby.

The video, obtained by The Daily Mirror, was filmed from a balcony of a nearby block of flats and shows one terror suspect, believed to be Michael Adebolajo, charging at police with a knife while his accomplice runs alongside with a hand gun.

Adebolajo gets within a few metres of a female police officer, armed with just a Taser, before another officer opens fire with two shots sending the suspect sprawling backwards.

Screams can be heard in the background as a further volley of six shots are fired by police at the other, unnamed, suspect. Both men can be seen writhing on the ground as officers with guns aimed order them to stay down.

Police have asked the public to provide any video or still images they have of the scene as they try to recreate events surrounding the brutal murder of Drummer Rigby with precise detail.

The attackers demanded onlookers record their actions on mobile phones and dozens of short clips have been provided to detectives investigating the case.

A total of four people including the two men shot by police have now been arrested in connection with the brutal attack.

Scotland Yard said a man and a woman, both 29, have been held on suspicion of conspiracy to murder and are being questioned at a police station in south London.

The two men who were shot, aged 22 and 28, have been arrested on suspicion of murder and remain in hospital in a stable condition with non life-threatening injuries.

Police watchdog the Independent Police Complaints Commission (IPCC) said it was not pursuing any criminal or misconduct offences in relation to the officers who used their weapons.

IPCC investigators have viewed CCTV of what happened, and said two officers fired guns and one discharged a Taser.

They have given initial accounts of what happened, IPCC commissioner Derrick Campbell said.

"Our investigation is as a result of the tragic events yesterday and I would like to express my sincere sympathies to the family of Lee Rigby at this terrible time,'' he said.

"The IPCC is independently verifying information regarding the circumstances of this incident and we can promise the Woolwich community, and wider public, that our investigation will be thorough.''

Meanwhile, Lincolnshire Police issued a warning to people on social media sites about making comments which could incite racial hatred, as its officers continued a search of a house in their area believed to relate to the attackers.

In a statement, the force said: "We would urge people to consider the very real impact of their online comments in relation to this matter.

“We have received a number of reports from local members of the public about tweets (on Twitter)and Facebook comments that could potentially incite racial hatred and violence.

“These are currently being investigated. If such communications are reported to us and they do breach the law, those messages may be monitored; captured and robust police action will be considered.”
