The trio killed seven people after mowing down revellers in central London before going on a rampage wearing fake bomb vests and wielding hunting knives.
The man who went on to wage a horrific attack on people at London Bridge previously appeared in a programme called The Jihadis Next Door on Channel 4 and was also thrown out of his mosque for ranting about an election.
A former friend of the Watford-born married father-of-two has revealed he contacted police about the terror thug’s extremist views, and claims he was radicalised after watching twisted YouTube videos.
