Update 3:30 p.m.
Officials in Ohio have released the names of the suspect in the Monday attack Ohio State University and the police officer who killed him.
Abdul Razak Ali Artan, an 18-year-old legal U.S. resident of Somali descent, injured 11 people when he rammed his car into a group of people on the campus Monday morning.
He then got out of the car and began stabbing people, before police officer Alan Horujko shot him dead.
The BBC reports that police are now investigating whether it's a terrorist attack.
Artan is said to have left Somalia within his family in 2007 and moved to Pakistan, before coming to the U.S. two years ago.
Nine people were hospitalized following a report of an active shooter at Ohio State University Monday morning.
But there is no indication that the suspect fired a gun during Monday morning's incident, officials said at a news conference Monday afternoon.
Hospital officials said Monday that the victims' injuries don't appear to be life-threatening. Eight victims are in stable condition and one victim is listed as critical.
The "chaotic" incident unfolded just before 9 a.m. (central time) Monday when the suspect drove over the curb and struck a group of pedestrians, then got out of the vehicle and stabbed people with a butcher knife, officials said at the news conference.
An officer, who responded to the scene in less than a minute, fatally shot the suspect. Officials said the quick action by the officer limited any additional injuries.
'Run, hide, fight'
The first alert related to the incident went out at 8:55 a.m., telling students there was an emergency on campus. Ohio State University Police tweeted there was an active shooter, telling students to "run, hide, fight." A shelter-in-place order was issued.
Numerous police vehicles, including officials from the ATF and Columbus Police Department, responded to the scene. After about 90 minutes the shelter-in-place order was lifted, with officials saying they had secured the scene, according to the university's website.
Classes will be canceled for the remainder of the day, and areas of the campus are still closed to the public as police investigate. Officials plan to hold another news conference later Monday.
Ohio State University is one of the largest universities in the United States with roughly 66,000 students.
