Bomb Threat


Typically, bomb threats are extremely rare; however, some bomb threats are received in the form of emails or handwritten messages. Most bomb threats are received by telephone. The person receiving the message or telephone call should remain calm and obtain as much information as possible by using the checklist below.  Do not hang up the phone, even if they do. It may help trace the caller’s location.  Use another phone, or signal a colleague to immediately call Campus Security at 626 395 5000.  Inform them of the situation with as much information as is available; specifically the location of device and time of possible detonation. Inform your immediate supervisor after informing Security.
