Description: "04/18/1975: After an anonymous telephone call at about 9:30 p.m., police found a bomb on a ground-floor window ledge of the north tower of National Defence headquarters (NDHQ). The bomb was placed in a ten by 12 inch brown leather satchel and comprised of a cigarette tin filled with five pounds of black powder, two batteries, a flash-bulb detonator, and a kitchen timer set to go off in two hours. Police and military personnel deactivated the bomb on the spot. NDHQ had received a bomb threat the previous evening; however, no bomb was found. The device was allegedly placed by the ""Weather Underground"" of the United States."
