Seattle Pacific University in Washington (SPU) was on lockdown this weekend due to a bomb threat. An unknown caller reportedly tipped the university that a bomb was scheduled to explode on one of the buildings on the campus, SPU officials said.

After receiving the bomb threat, Seattle Pacific University held a lock down and evacuated some buildings in the campus. This included the Royal Brougham Pavillion where students were gathered for a fashion hosted by the SPU MODE Fashion group. The annual event was postponed and it is currently unknown if the club will be rescheduling the fashion show, Fox 13 reported.

According to Donald W. Mortenson, SPU's Safety and Security Senior Vice President for Planning and Administration, the bomb threat was not credible but they proceeded with taking measures to protect Seattle Pacific University staff and students. The lockdown was lifted Sunday night and the authorities did not find anything during their search and sweep of the campus. Furthermore, there were no students who got hurt or were missing.

Prior to the lockdown lift, some of the students were asked to leave some areas in the campus while some were told to stay in shelters in SPU. There were no further details as to who sent the bomb threat message or why it was sent in the first place, BNO News shared.

The officials are still on high alert after the bomb threat was cleared, Q13 Fox noted. On June 2014, a gunman entered Seattle Pacific University and went on a shooting spree. It resulted in four people injured and one death. SPU is a private university located in downtown Seattle and attended by more than 4,000 students.
