COLUMBUS, Ohio — Ohio State University says an shelter-in-place warning has been lifted and the scene is secure following an active shooter report and injuries.

At least seven people were transported to local hospitals, one in critical condition, according to Columbus Police emergency dispatch communications.

"Buckeye Alert: Active Shooter on campus. Run Hide Fight. Watts Hall. 19th and College" the university's emergency management agency tweeted. Later the agency tweeted a warning to "Continue to shelter in place in north campus area. Follow directions of Police on scene."

A similar message appears atop the school's website: "Buckeye Alert: Continue to shelter in place. Avoid area of College. More information to follow."

The school's website lists Watts Hall as a Materials Science and Engineering building.

"Ohio's thoughts and prayers go out to the Ohio State community," Gov. John Kasich tweeted. "Be safe, listen to first responders."

Tweeted Rep. Tim Ryan, D-Ohio: "Everyone stay safe -- Monitoring this situation closely. Thoughts and prayers with everyone on campus."

Ohio State’s 1,764-acre campus is located about 2.5 miles north of Columbus. The school, founded in 1870, is the third-largest campus in the U.S. with about 45,000 undergraduates and 13,000 post-graduates.
