A bomb threat made early Friday (August 26) forced students at Howard University to evacuate two residence halls for the second time during the first week of fall semester classes.

According to NBC Washington, D.C. investigators checked out the threat and found nothing. A university spokesperson said police may know where the call originated.

“For the second time in 48 hours, students have had to evacuate residence halls during the late hours of a school night,” Howard University President Wayne A. I. Frederick wrote in a letter to students, noting this was the eighth bomb threat to the university in 2022. “People who love and care about them, parents, university employees, alumni, and so many others, have had to wrestle with anxiety about the veracity of another terroristic act.”

Howard University police say the threat was received just after 2:30 a.m. on Friday and targeted the East and West Towers on campus, which house up to 1,800 students.

“We were sleeping in the middle of the night and, like, the fire alarm went off and we weren’t sure what was going on,” a student told the news station. “We just had one earlier, so everybody just left the building — same as we did before.”

A Howard spokesperson said in a statement that human, animal and mechanical explosive-finding devices were used in the search of the two residential buildings.

The university notes it’s in contact with federal officials, who have been assigned to investigate similar threats.

"We appreciate the support of the MPD and members of the bomb unit for their quick response," the statement from the university adds.

Late Tuesday, another bomb threat forced students to evacuate Cook Hall. The D.C. police department’s bomb unit responded and gave the all-clear early Wednesday.
