Authorities in Grand Rapids are investigating shots that struck the city's main firehouse.
Police say Friday that three "projectiles" hit the building.
Fire Chief Laura Knapp tells WOOD-TV that "there's no indication that the LaGrave Street fire station was targeted or firefighters are being targeted."
Two of the slugs struck separate bay doors at the building.
A shot also hit a second-story window.
The damage was discovered Wednesday morning. Officers responded late Tuesday night to reports of gunfire in the area and found three shell casings.
A witness said shots were fired during a confrontation involving a group of men.
