SAN FRANCISCO, Sept. 24 (Xinhua) — A lone suspect, identified as Arcan Cetin, was arrested Saturday night for his role in a mall shooting in the northwestern U.S. state of Washington.

Cetin was reportedly arrested around 7:00 p.m. local time Saturday night (0200 GMT on Sunday), less than 24 hours after the mall shooting.

In addition to providing the name of the gunman, Sergeant Mark Francis, a public information officer with Washington State Patrol, posted on Twitter that the man in custody is a 20-year-old resident of Oak Harbor.

KING-TV in Seattle reported that the gunman was apprehended in Oak Harbor, about 29 miles, or 47 kilometers, southwest of Burlington, a small town where the gun-shooting incident took place Friday night.

Security camera images showed that the shooter first entered the mall, apparently without a weapon, and then held a rifle in front of a store. The images were posted by authorities as part of an effort to seek public help to hunt down the suspect.

The fatalities, initially four women at the makeup section of Macy's department store and one vendor at Cascade Mall, were revised Saturday morning to include a male who did not survive life-threatening injuries from the incident.
