title: Canadian police say suspect in Edmonton attacks is Somali national
text: TORONTO (Reuters) - Canadian police told a news conference on Sunday that a suspect arrested following Saturday night s attacks in Edmonton was a Somali national with refugee status in Canada.  Police declined to provide his name but said authorities had investigated a complaint in 2015 that he was espousing extremist ideology and had determined that he did not pose a threat at the time.  (This version was corrected officially to change the first paragraph after the police corrected original statement to say suspect is a refugee, rather than seeking refugee status)
