A 12-year-old boy was hospitalized after being hit by shotgun pellets from a hunter over the weekend in Washington County, wardens said.

The boy’s father was shooting at a grouse and some of the pellets hit his son, WABI-TV reported.

The boy was transported to Northern Light Eastern Maine Medical Center in Bangor, wardens said.

The Maine Warden Service declined to release identities and the shooting remains under investigation. Officials did not say what type of shotgun pellets hit the boy. Buckshot is larger than birdshot.
