 "Eight hurt in Ohio State campus attack, shooter dead")
Eight people were injured when an attacker apparently drove into a crowd at Ohio State University today, triggering an hours-long lockdown before authorities declared the campus secure.
Law enforcement shot and killed one suspect, according to local television station WBNS, which reported that police led two people out in handcuffs from a garage they had surrounded on the university's main campus in Columbus.
A witness suggested that a suspect was driving a red SUV.
The incident was called an active shooter situation, but it was unclear whether any of the victims had suffered firearm injuries.
Some reports suggested the attacker or attackers used a knife.
"Shelter in Place lifted. Scene is now secure. ALL classes are canceled on Columbus campus for the remainder of the day," the OSU emergency management services tweeted as it declared the incident over.

Television footage showed students leaving school buildings as Rebecca Diehm, spokeswoman for the Columbus fire department, said eight people had been transported to hospital.
One was in critical condition, and the rest were stable, she said.
OSU Wexner Medical Center tweeted that it was treating four victims, none with life-threatening injuries.
Earlier the university's emergency management service had urged students and staff to shelter in place amid reports of an active shooter, as SWAT teams fanned out across the facility.
"Buckeye Alert: Active Shooter on campus. Run Hide Fight.
Watts Hall. 19th and College," the service said in a tweet. A second tweet moments later told the public to "Continue to shelter in place. Avoid area of College." Details were murky as the situation unfolded. One student told MSNBC she was walking along a road on campus when a car plowed into a group of people, including a police officer.
Another student, Joseph Noll, said he heard a fire alarm, but no shooting -- and also said a car had driven into the crowd.
"I was right there, and there was no one shot," he told WBNS. "Someone DID run over a crowd of people with their car.
I can tell you that for sure."
"I just heard some screams, and I saw people running," he said. "And everyone just fled the scene immediately."
