A heavyweight Islamic State (Isis) executioner known as 'The Bulldozer' is believed to have been captured by the Syrian Army. The 20-stone jihadist has been accused of a series of brutal beheadings and crude amputations of limbs belonging to children.

The obese Daesh (Isis) terrorist, whose true identity is not known, has been seen in previous videos decapitating Kurdish Peshmerga soldiers. He earned his nickname in June 2014, after he was pictured holding a 5ft-long, 52kg Browning machine gun, loaded with armour-piercing bullets all by himself.

A member of the infamous Isis Chopping Committee, that has terrified areas of the self-declared caliphate, he is said to have been pictured being captured by the Syrian Armed Forces in a new video posted online by the Department of Film and Sound Young Journalists Club.

In the footage, the chubby jihadi is seen stripped naked from the waste up, with his hands tied behind his back, after being thrown on the back of a vehicle whilst taunted by his captives. He is then driven away — presumably to a jail somewhere in Syria. It is not known where in the war-torn nation the footage was captured.

The Bulldozer has been recorded executing his victims in front of large crowds using a three foot blade. Often pictured wearing a mask The Bulldozer is suspected of being an Iranian national. He is believed to have first been filmed executing Isis opponents in Iraq, then Syria.

In 2015, a 14-year-old Syrian boy said the fat extremist chopped off his hand and foot because he refused to join the terrorists. Last month the masked terrorist seemingly appeared in a brutal new video released by the terror group, in which a man's head was crushed by a boulder.

The footage, captured in a video entitled 'Crush Your Enemies', believed to have been filmed in Yemen The Bulldozer hacks off the head of one prisoner with a knife, before placing the severed head on the corpse's back as it lies in dirt. A second soldier is tied to a chair and repeatedly shot, while a third is murdered by having a large boulder dropped on his head.
