The ISU Police Department has no updates in the investigation of a bomb threat to Durham Center that caused the department to evacuate and search the building early Monday morning. 

After a search, the department found no suspicious objects in the building. 

Though they do not have a suspect in mind as to who placed an 11-minute phone call to the department threatening to bomb Durham Center, ISU Police Capt. Aaron DeLashmutt said the department will continue to try trace the call and locate the caller. 

While Parks Library was evacuated at about 1 a.m. Monday, police had surrounded the Durham Center, which still had some students and faculty members in the building. DeLashmutt said some faculty members chose to stay in their office in Durham while police searched the building. 

“We are obviously always monitoring the situation, and we try to keep everyone updated,” DeLashmutt said. 

The anonymous threat was placed to to the ISU Police Departments some time before 12:50 a.m. Monday when the unidentified caller indicated there was a bomb in Durham Center.

The phone call, which lasted about 11 minutes, resulted in a search of the building where nothing suspicious was found. Officials gave the all-clear and began to leave the area around 5 a.m. Monday.

Students and staff were notified of the bomb threat just before 1 a.m. Monday by an ISU Alert and were told to avoid the area. A S.W.A.T. team was called onto the scene, as well. 

Police officers completed their investigation of the Durham Center and issued an all-clear for the building at 5 a.m. Monday.

Anyone with any information about this case or who sees suspicious activity is asked to immediately contact ISU Police by calling 515-294-4428 or 911.
