FBI headquarters received the threat on Tuesday morning, according to The Associated Press, stating that explosives had been placed in four buildings on the university's campus.
Campus security was notified by 8:19 a.m., and the university released its "Buckeye Alert" by 8:41 a.m., cautioning students and faculty to stay clear of the buildings identified in the threat: the William Oxley Thompson Memorial Library, the McPherson Chemical Lab, Smith Laboratory and Scott Laboratory.
Classes in the lab buildings were canceled, and campus security advised everyone to stay clear of the locations until at least 5 p.m.
Three streets around the campus were also closed off.
School officials said the search, which utilized bomb-sniffing dogs, has not yet recovered anything.
"This is still in our assessment a threat, and there have been no suspicious package or devices found at this time," university Police Chief Paul Denton said at a news conference.
