A building was left significantly damaged following an explosion in Ellwood City on Tuesday morning.
The blast happened just after midnight on the 600 block of Mount Vernon Drive.
The explosion tore through what used to be a school building now home to several small businesses, including a local brewery, the Time Brew Pub.
The cause of the explosion is still under investigation, but officials say a gas leak is the likely culprit.
Columbia Gas and the State Fire Marshal are both assisting alongside the ATF, which has been notified due to the scale of destruction.
No one was inside at the time and no injuries have been reported.
