After graduating from university in May 2009, Emwazi flew to Tanzania with friends apparently on a safari - but was arrested by police upon landing in Dar es Salaam and sent back to Britain.
En route he stopped in Amsterdam, where he claimed to have been accused by an MI5 officer of trying to reach Somalia, home of the militant group Al Shabaab.
Emwazi claimed to have been harassed and intimidated by security services - and even complained to the Independent Police Complaints Commission.
He alleged an agent from MI5 knew 'everything about me; where I lived, what I did, and the people I hanged around with' and claimed the organisation attempted to 'turn' him to work for them. http://www.dailymail.co.uk/news/article-2970161/ISIS-executioner-Jihadi-John-identified-London-man-Mohammed-Emwazi.html
