Fire damaged a vacant house in Madison Township Tuesday morning.

A passer-by called firefighters after seeing thick white smoke billowing from the one-story house at 337 Pennsylvania Avenue.

The Madison, Mansfield, Mifflin, and Franklin Township fire departments raced to the scene.

Madison Fire Chief Chris Niswander says the blaze broke-out in the basement crawl space, and burned several holes in the ground floor, which sustained heavy smoke damage.

The state fire marshal was called-in to help investigate the cause, which for now is considered suspicious.

No firefighters were hurt while battling the smoky blaze.
