BUTLER (KDKA) — A lockdown at a Butler County elementary school has been lifted after a bullet hit the building Tuesday afternoon.

According to Acting Superintendent Dr. William Pettigrew, the McQuistion Elementary School was briefly placed on lockdown around noon.

Dr. Pettigrew said a stray bullet struck a window at the school and fell to the ground. The window was not penetrated.

“The police were called and it was discovered that a bullet had hit the window, broke the window and fell directly below the window,” Dr. Pettigrew said.

McQuistion Elementary was immediately put on lockdown and afternoon kindergarten was cancelled, because of uncertainty about the situation.

“The rest of our schools were put on perimeter lockdown, and by 12:30, quarter to one, the lockdown was lifted,” Dr. Pettigrew said.

Butler Township Police say the bullet never entered the building, and although there were people both inside and outside, no one reported hearing a gunshot.

Police say evidence at the scene leads them to believe the bullet might have been a stray from a hunting rifle and fired from a considerable distance away.

State police were called to the scene to investigate.
