The man at the centre of a network that influenced the ISIS executioner identified as 'Jihadi John' was allowed to fly in and out of London to terrorism hot spots unchecked for almost three years. Bilal al-Berjawi passed through UK Border Control at least five times between 2006 and 2009 as he travelled between London and African terror cells. Over that period he was rising to prominence as a senior member of al-Shabaab, the al-Qaeda linked group in Somalia - returning to the UK only to raise funds and to marry. Scroll down for video Lebanon born Bilal al-Berjawi (right) traveled freely between the UK and terror hubs in East Africa as he rose to prominence with al-Qaeda. He is believed to have radicalised Mohammed Emwazi (left) - revealed earlier today as the masked ISIS executioner Jihadi John - on his return visits to London
