 Mostly cloudy and 70 degrees in Fond du Lac, mostly cloudy overnight with a low of 56. I'm Doug Ratflick in the SSM Health News Center. The Fond du Lac Sheriff's Office assisted the Waupon Police Department with a tactical call in the central portion of Waupon early this morning. The incident started just before midnight with a domestic disturbance call at an East Franklin Street address. As officers responded to the area, a call came in a short distance away of the man involved holding an axe trying to get into a residence.
