No devices were found after searches were completed in the four Ohio State University campus buildings that were named in a bomb threat on Tuesday morning.
According to the university, searches at McPherson Chemical Lab and Smith Laboratory were completed and the buildings reopened on Tuesday evening.
All activities and classes inside McPherson and Smith were to resume at their regularly scheduled times.
Scott Laboratory reopened at 6 p.m. Tuesday. The William Oxley Thompson Memorial Library reopened at 9 p.m.
According to the university, the library opened later because personal property left during the evacuation had to be collected. It will be gathered up and placed at the west security desk and may be picked during regular library hours.
Any personal items left in McPherson, Smith or Scott may be retrieved at Blankenship Hall, located at 901 Woody Hayes Drive, between 8-11 a.m. and from noon to 2 p.m. on Wednesday.
"The university puts the highest priority on the safety of our students, faculty and staff," said Vernon Baisden, assistant vice president and director of public safety. "Throughout the day our public safety forces have meticulously checked the affected buildings to insure that our students continue to have a safe learning environment."
The anonymous threat was sent to the FBI's Washington Bureau, and agents there notified authorities in Columbus, 10TV's Kevin Landers reported.
The threat said there were several explosive devices inside the library, along with McPherson, Scott and Smith laboratories, Baisden said.
In response to the threat, police used the Buckeye Alert system to send more than 30,000 text messages, telling students and staff to stay away from the buildings and surrounding areas.
Video from Chopper 10 showed police taping off areas outside of the library. Officers with dogs were also in the area. Some officers were seen peering into the windows of parked vehicles.
