The calls were released by authorities hours after Abdul Razak Ali Artan, 18, launched his rampage.

“I think this is some type of terrorist attack,” one person told the 911 operator.

“There's a guy, crashed his car into a bunch of people and ran out with a knife chasing down people,” another said.

Artan borrowed a car from a family member Monday when he started his rampage. He used the car to jump a curb and strike pedestrians walking to class.

He got out of the car, reportedly wielding a butcher knife, and slashed several people in the area, officials said.

None of the injuries were considered life-threatening, though at least two of the pedestrians hit by the vehicle underwent surgery.

"I heard someone yell, 'he's got a knife,' and I saw a guy with a big-ass knife just chasing people around," OSU student Jacob Bowers told NBC News. "When I saw that, I grabbed all my stuff and started running."

Bowers added that “the man was going insane” prior to being gunned down by Officer Horujko.
