New Delhi: The 'new Jihadi John', Siddhartha Dhar, who appeared in the latest ISIS video threatening UK is believed to be an Indian-origin British Muslim convert.
After watching the video, Dhar's family claimed that they have noticed some similarities between the voice of the masked man and their son but they are not sure about it.
One of Dhar's former business associates claimed that he had no doubt the voice on the video was that of Dhar.
In the video released on Sunday, before executing five men who appeared shackled and dressed in orange boiler suits, a masked ISIS man with British accent threatened to invade the UK and called British PM David Cameron an 'imbecile'.
The footage revived memories of 'Jihadi John' - a British ISIS member who in past appeared in several videos in which hostages were killed before his own death was reported in an air strike late last year.
