Lakehead University students and staff are being welcomed back into the
Centennial Building after fire alarms were pulled this afternoon.
School Spokesperson Toby Goodfellow says discarded cigarette butts fell
into a grate catching little pieces of paper on fire. The smoke then
traveled up the exhaust system and into the building. The building was
evacuated this afternoon while fire fighters went room to room to find
the cause of the smoke.
