One of the masterminds behind the Sri Lanka suicide bombings lived in London and spent a year at Kingston University on an aerospace engineering course, The Telegraph can disclose.

The Islamic State terrorist, named today as Abdul Lathief Jameel Mohamed, spent a year at the university in south west London in the academic year 2006 to 2007, according to well-placed sources, before travelling to Melbourne in Australia for a postgraduate course.

Intelligence agents are now combing through connections made in the UK to examine whether he could have been radicalised in this country - and whether he could have been in contact with jihadists at that time.

Intelligence officers will also be looking at the travel plans of two wealthy brothers, who blew themselves up at the Shangri-La and Cinnamon Grand Hotels, killing scores of tourists including a number of Britons. One of the brothers Inshaf Ahamed Ibrahim, 33, flew frequently around the world, including trips to the UK, according to a source at his family-owned spice trading company where he was the export director.

In 2015, David Cameron, when prime minister, ‘named and shamed’ Kingston among four universities which he alleged had hosted the most events with extremist speakers. The naming of Kingston followed a study by the Government’s newly established Extremism Analysis Unit.
