At least nine people have reportedly been injured during a knife attack at Ohio State University in Columbus, Ohio.
The incident was originally reported as an active shooter situation.
Police confirmed to a local NBC News affiliate that one suspect is dead. Law enforcement authorities said the suspect drove a car into a crowd then began to cut people with a butcher knife. A police officer shot the suspect after arriving on the scene within minutes after the attack began.
One of the nine victims is said to have critical injuries. All victims were transported to local hospitals for treatment.
OSU’s emergency alert system sent texts and tweets to students at approximately 10am ET on Monday morning, telling them, “Run Hide Fight.” The incident occurred in Watts Hall, a science and engineering building.

“Run, hide, fight” is a common strategy, promoted by security professionals, for how to handle a mass shooting scenario and should be used as a checklist for how to react when confronted by an active shooter. The first option should be to run if you can. If that’s not a safe option, you should hide. With no other options available, fight.
The university has asked the OSU community to take shelter and avoid calling police unless they have new information.
Buckeye Alert: Continue to shelter in place in north campus area. Follow directions of Police on scene.
