Kuwait-born Emwazi lived in west London and attended the University of Westminster before fleeing England and travelling to Syria in 2012.
The picture appears to have come from a student profile of Emwazi from the University's system. The profile suggests he studied Information Systems with Business Management as a joint honours degree between 2006 and 2009, passing all but two modules. Jihadi John became a symbol of the unwavering brutality underscoring Isis when he appeared in several videos showing the beheading of Western journalists and aid workers.
Emwazi was named by friends quoted in The Washington Post as the man behind the mask in footage released by Isis.

A picture emerged today purporting to show Emwazi as a child sitting with his former classmates in primary school.
The 27-year-old was reportedly described as a keen footballer and a diligent student by former friends and teachers.
An international manhunt was launched in 2014 when he was believed to have appeared in a video showing the beheading of the photojournalist James Foley.
