Muskegon County Sheriff Dean Roesler said emergency personnel showed up at the man's Dalton Township home Sunday evening after neighbors found him slumped over in a chair. Roesler said the unidentified man perked up after the crew arrived, said he was "heavily armed" and didn't want "to be bothered."
Roesler said the man later jumped into a department vehicle, drove around his house and parked it behind the property. He then fired what is believed to be a high-caliber hunting rifle.
Officers used a stun gun to subdue the man, who was arrested.
No injuries were reported. The vehicle sustained no damage.
