Home Affairs Minister Tony Burke says security agencies are tracking an ISIS-linked Australian woman accused of violently enforcing sharia law at detention camps in Syria.Hodan Abby is the last-known ISIS bride in Syria.She was barred from returning to Australia under a temporary exclusion order in February – the only one of a cohort of Australian women and children.But she was last month given a permit to return after the order was revoked.Noting that there was “a reason why only one person met the threshold for an exclusion order”, Mr Burke said on Monday that Ms Abby would have the “full attention from our agencies” should she make it to Australia.“Our agencies are aware of aware of her location, but obviously she may well, having seen some people who returned, be arrested on arrival at the airport,” he told ABC’s News Breakfast.“She’d be weighing up the different things that she’s done and would be making a decision as to whether or not she, in fact, ever returns.”Regardless, he said investigators would “continue to build evidence”.“Sometimes people have been arrested at the airport,” Mr Burke said.“Sometimes … we’ve continued to get collect additional evidence after their arrival, and arrests have happened later.”Ms Abby gained a reputation as an ISIS enforcer during her time at the Kurdish-run al-Roj detention camp in Syria’s northeast, the ABC reported, citing sources in the camp.In one particularly violent incident, she allegedly hit another woman with a hammer.More to come
