The young Jihadi bride who fled the UK to join Isis was "a member of the feared Isis morality police' in Syria", the Telegraph reported.
Shamima Begum, 19, who joined Isis as a 15-year-old, has always claimed she was "just a housewife" during her four years under the brutal Islamic State.
But now it has been alleged the teenager spent her days assisting suicide bombers by stitching them into suicide vests, carried a Kalashnikov rifle and enforced strict dress code as part of her role in the feared Isis morality police department.
The latest information about Begum was obtained by an allied spy agency and presented to British Prime Minister Theresa May and Home Secretary.
It is believed the information came from the CIA and Dutch Military Intelligence – during interrogation of other Western Isis converts.
