The roof of a former Pfaltzgraff buidling in Jackson Township was reported to have collapsed, and crews were dispatched to the 75 Bowman Road building, currently used by BAE Systems, about 8 p.m., according to York County 911.

But a fire official on the scene has said there was no collapse, and it is unclear how the alarm came about -- whether someone called it in or it was triggered by alarm equipment.
