RALEIGH, N.C. — North Carolina Central University sent out an "all-clear" message Tuesday night, about four hours after a bomb threat prompted the Durham campus to evacuate.
The university was one of at least seven bomb threats reported Tuesday at historically black colleges and universities around the country, the university said in a statement.
None of the threats resulted in a bomb or explosive being found.
The alert sent to NCCU at 5:34 p.m. Eastern time told the campus community to "proceed immediately to the nearest exit and vacate the building." Officials told employees to return home.
Students who couldn't go home were told to report to Hillside High School's parking lot.
"This is not a drill," the alert said in all capital letters.
The Campus Echo, the student newspaper, confirmed a bomb threat was reported about 5:35 p.m.
The university later tweeted: "All students who require transportation off campus to the evacuation point should report to the Lower Lot of the Mary Townes Science Complex parking lot."
By 9:15 p.m., an all-clear message was sent and students were taken back to their residence halls.
The following agencies investigated the threat: NCCU Police, Durham Police, Durham County Sheriff's Office, Durham Fire Department, Bureau of Alcohol, Tobacco, Firearms and Explosives and Durham City/County Emergency Management. N.C. State University and UNC-Chapel Hill Police Departments also assisted in confirming buildings were cleared safely.
