Jamshed Javeed, 30, had been a respected science teacher at Sharples High School in Bolton and regarded as a moderate Muslim. But he had become radicalised by the preachings of, among others, Anwar al-Awlaki, an al-Qaeda spiritual leader, so that in 2013 he had helped to pay for his brother Mohammed, then aged 20, to travel to Syria with two fellow students Khalil Raoufi, 20, and Raphael Hostey, 22. Raoufi was killed fighting for Isil last year and Javeed’s brother is also thought to have died.
