British security agents try to identify the masked militant who spoke in clear English accent in a new ISIS execution video released recently in which he is seen shooting an alleged British spy.

Reports have been circulating that the man could be Siddhartha Dhar, a British militant who got away with his family when Scotland Yard conducted an investigation about him in 2014, as Daily Mail reports.

Dhar’s sister also fuelled speculation when he said that she believed the ISIS gunman sounded very much like her brother.

Dhar, who is also known as Abu Rumaysah, is believed to have met, and possibly mentored, Michael Adebolajo, one of the murderers of Fusilier Lee Rigby.

According to director of international security studies at Royal United Services Raffaello Pantucci, the executioner’s voice sounded like Dhar’s.

He said: ‘He sounds a bit like Abu Rumaysah from Al-Muhajiroun videos. From watching him in Al-Muhajiroun videos and this new video he sounds very similar.’

Online news magazine VICE, which interviewed Dhar in 2014, believed the executioner’s ‘voice and speech pattern’ was similar to Dhar.

Several Twitter users, including Al Rai correspondent Elijah Magnier, have also claimed that it is likely he is the gunman.

Dhar had been arrested in September 2014 but released on bail and ordered to hand in his passport.

But immediately after, he left UK with his family heading to the ISIS war zone.
Dhar boasted on Twitter how police clumsily allowed him to slip through their fingers: ‘What a shoddy security system Britain must have to allow me to breeze through Europe to the Islamic State.’

And that he he had fooled MI5: ‘My Lord (Allah) made a mockery of British intelligence and surveillance. Make hijrah (flight) Muslims. Place your trust in Allah.’

As Daily Mail reports, Dhar was repeatedly interviewed by BBC and Channel 4 expressing his radical views and publicly stating that he wanted to live under the Islamic State in Syria.
