A 60-year-old Madison man has been tentatively charged with substantial battery after hitting his neighbor in the head with a baseball bat. Police say the two residents on the city’s north side have been feuding. Steven Krajewski was arrested Sunday morning. The victim’s name hasn’t been released. He fell to the ground after being hit and was taken to a nearby hospital with concussion-like symptoms. A police spokesperson calls the situation an “ongoing conflict” between the two.
