Suspect in latest IS propaganda used to sell bouncy castles for a living

The main suspect in the latest propaganda video by so-called Islamic State (IS) is thought to be British man Siddhartha Dhar, the BBC reports. Dhar used to sell bouncy castles for a living. He quit his life in London, where he supported the Arsenal team, and joined the insurgency. 

An official source said Dhar was the focus of investigations into the video, which purports to show the killing of five men IS says were spies.

Dhar, also known as Abu Rumaysah, fled Britain in 2014 while on bail.

The father-of-four, from Walthamstow in east London, had been arrested on suspicion of encouraging terrorism, but later travelled to Syria after being bailed.

In the latest video by the extremist group - which has not been independently verified - the masked man, who is holding a gun, mocks Prime Minister David Cameron for daring to "challenge the might" of the extremist group.

He goes on to say: "We will continue to wage jihad, break borders and one day invade your land where we will rule by the Sharia."

Cameron said the video was "desperate stuff" from a group that was "losing territory".

In the video, five men, wearing jumpsuits and kneeling in a desert location, appear to be shot in the back of the head, after making what is claimed to be their confessions. IS says they were spying for the UK.

One of the men says he had been asked to provide information about the location of IS militants, including two Britons, apparently to help target them with air strikes.

IS has previously released propaganda videos of killings, including footage showing the apparent beheading of two US journalists, James Foley and Steven Sotloff, and two British aid workers, David Haines and Alan Henning.
