Never-before-seen video has emerged of the moment a battered and bleeding Colonel Gaddafi was captured by Libyan rebels.

The shocking footage was captured on the mobile phone of one of the fighters who dragged the dictator alive from a drain in Sirte in 2011.

Similar footage was widely circulated at the time of his death, but this video captures his final moments from a new perspective and clearly shows him pleading for his life.

It shows frenzied scenes as Gaddafi is surrounded by screaming gunmen on the bonnet of a truck minutes before he was summarily executed.

The Libyan leader can be heard begging for his life as one rebel points a handgun at his head which is covered in blood.

The footage was taken by rebel fighter Ayman Almani, who was tracked down by BBC reporter Gabriel Gatehouse in the Libyan city of Misrata more than four years later.

Almani said: 'He deserved it. Islam teaches us not to mistreat a prisoner, not to bear a grudge.

'But the people got carried away in the stampede and no-one could stop them.'

His footage, which he has never made public before, is the latest in a series of harrowing mobile phone videos documenting Gaddafi's final moments.

Symbol of victory: Libyan teenager Mohammed al-Bibi (right) is pictured alongside the golden gun which is said to have been used to kill Colonel Gaddafi. He has denied that fired the fatal shot, saying he simply came across the weapon on the floor and in the chaos became known as the executioner

In other clips, he can also be heard pleading for mercy and demanding to know what he had done wrong while enduring a series of crunching blows to his face and head.

One particularly horrific clip appeared to show a knife being repeatedly inserted into his backside while he was standing up.

In his final breaths, the bloodied dictator was taunted with a pistol before a single shot rang out followed by silence.

Gaddafi was said to have been executed by his own personal golden gun which was held up in celebration by jubilant rebels and became a symbol of their victory.

Mohammed al-Bibi, who was pictured in a baseball cap brandishing the weapon at the time, today insists he did not fire the fatal shot.

He told the BBC he simply came across the gun on the ground and in the confusion became known as the executioner.

He says he still receives death threats from Gaddafi loyalists to this day.

The astonishing end for the tyrant came after he and loyalist fighters tried to flee Sirte as it was overrun by forces of the National Transitional Council with he help of RAF airstrikes.

Gaddafi was in a convoy of up to 100 vehicles which tried to break out of Sirte – the last centre of resistance after eight months of civil war – early yesterday.

The escape was spotted by Nato which launched two devastating strikes. At least 50 loyalist fighters were killed.
