Self-esteem problems : Mohammed Emwazi was even given anger management therapy at school . Fellow secondary school pupils bullied Mohammed Emwazi - calling him ‘ Little Mo ’ , it emerged yesterday . Emwazi - revealed last week as Jihadi John - was also said to have self-esteem problems and was even given anger management therapy at Quintin Kynaston school in north-west London . A former friend said a gang of older teenagers used to wait outside the school for Emwazi , then 14 and smaller and weaker than other boys his age . ‘ They would steal his lunch money and push him around a bit , ’ he said . ‘ He was very quiet and a bit scrawny back then so we used to call him Little Mo. ’ The St John ’ s Wood school is subject to a Department for Education investigation after it emerged that at least three past pupils have joined Islamist terror groups and contemporaries of Emwazi have claimed young Muslims were ‘ groomed ’ by radicals . Its former headmistress , Jo Shuter , said she recalled Emwazi was bullied when he was 14 , but denied there had been a problem with radicalisation . She told the BBC yesterday : ‘ He had some issues with being bullied , which we dealt with .
