Abu Rumaysah, also known as Siddhartha Dhar, is reported to have traveled to Syria with his family after fleeing the UK while on conditional bail. The Islamist convert was one of nine people arrested on September 25 on suspicion of supporting the banned terrorist organization al Muhajiroun.

Two days after his arrest, Rumaysah failed to comply with bail conditions requiring him to hand in his travel documents and instead boarded a coach from London to Paris with his wife and four children, which was reportedly headed for Syria.

After weeks of speculation concerning his whereabouts, Rumaysah posted an image to Twitter showing him posing with a baby and an automatic rifle. He claimed that he had made it to the Islamic State. "What a shoddy security system Britain must have to allow me to breeze through Europe to the Islamic State," he wrote.

VICE News spent time with Abu Rumaysah before he fled to find out more about his activities in imposing Sharia law in the UK and his views on foreign policy. We also interviewed radical preacher Anjem Choudary, who was arrested on the same charge, and spoke with him about Rumaysah's exit from the UK.
