A suspect has been apprehended and taken into custody following the fatal shooting of five people at a shopping mall in Burlington, Washington state, on Friday evening (September 23).
Washington state police say 20-year-old Arcan Cetin was arrested in Oak Harbor, some 46 kilometres from the site of the rampage.
A manhunt had been underway since the rampage at the Cascade Mall, with the suspect initially being described as a male, aged between 20 and 25, who was wearing a black t-shirt.
A surveillance camera image was released in which the suspected gunman appeared to be carrying a rifle.
Police said they believed he acted alone. No motive for the attack was given and there was no indication of a link to any previous violent incident.
