'Self-Publicist' Who Fled UK While On Bail

As security services try to identify the Briton featured in the latest Islamic State video, there is speculation it may be jihadist Siddhartha Dhar. The 32-year-old was born a Hindu, but converted to Islam around a decade ago, taking the name Abu Rumaysah. He lived in Walthamstow, east London, and reportedly ran a business renting out bouncy castles before converting and becoming radicalised.
