COLUMBUS, Ohio — An Ohio State student drove a speeding car into a crowd outside a classroom building Monday morning, then got out and slashed at people with a large knife, sending 11 people to the hospital in what authorities said was a planned assault. University public safety officials identified the student as Abdul Razak Ali Artan. Officials said they had no information on a possible motive and said that campus video cameras showed Artan was alone in the car.
