At least eight people were stabbed, hit by a vehicle or otherwise injured in an attack Monday morning on the Ohio State University campus, and a suspect was shot, school and hospital officials said.
Police did not immediately release the suspect's condition and gave no details on a possible motive. Hospital officials said the eight victims had non-life-threatening injuries.
The university had warned students in a series of tweets earlier Monday that there was an active shooter on campus and that they should run, hide or fight. About an hour and a half later, the university said a shelter-in-place warning had been lifted and the scene was secure.
Some of the victims had been stabbed and others were hit by a vehicle, said Ben Johnson, a university spokesman. Some of the other injuries were being evaluated, he said.
The eight patients were split among OSU Wexner Medical Center, OhioHealth Grant Medical Center and OhioHealth Riverside Methodist Hospital.
The Fire Department had earlier said that seven people had been taken to hospitals.
It wasn't immediately clear if a suspect or suspects in the attack were among the people sent to the hospitals.
Cassidie Baker, an Ohio State senior, said she saw police or paramedics helping one person on the ground outside Watts Hall.
"No one really knows what is happening, other than there's an active shooter," she said.
Ohio State said about an hour and a half after its initial tweets about an active shooter that a shelter-in-place warning had been lifted and the scene was secure. The university tweeted that all classes would be canceled for the rest of the day.
At 9:56 a.m. EST, the university's emergency management department tweeted "Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College." Watts Hall is a materials science and engineering building.
"Run, hide, fight" is standard protocol for active shooter situations. It means: Run, evacuate if possible; hide, get silently out of view; or fight, as a last resort, take action to disrupt or incapacitate the shooter if your life is in imminent danger.
The university followed up with another tweet: "Continue to shelter in place in north campus area. Follow directions of Police on scene." The university asked for anyone with information to call police.
At 11:30 a.m. EST, OSU Emergency Management tweeted: "Shelter in Place lifted. Scene is now secure. ALL classes are canceled on Columbus campus for the remainder of the day." It also advised that certain buildings and areas on campus were closed.
Many police vehicles were at the scene. No other information was immediately available.
With nearly 60,000 students at its main Columbus campus, Ohio State is one of the nation's largest universities.
