STOCKHOLM (AP) — Swedish authorities are investigating whether an knife attack by an Afghan man who stabbed seven men and left three of them in critical but stable condition had any links to terrorism. The suspect, who was not named under Swedish policy rules, now faces several counts of attempted murder. Home Affairs Minister Mikael Damberg said on Thursday that “initial information” led police to believe that they should at terrorism as a possible motive for the attack. Neither Damberg nor police would elaborate what that “initial information” was to prompt investigators to probe possible terrorism links. Media reports said the suspect had been waiting to see if his residence permit would be renewed, although the Swedish Migration Board declined to confirm that.
