But disputes over fence posts can apparently turn none too neighborly, as evidenced by a Kingsport man's arrest for an alleged pepper spray attack.Bobby G. Williams, 66, of 1753 McGee Street, is charged with aggravated assault in the Tuesday incident. A Kingsport police report says that shortly after noon his neighbor called police, saying he'd been doused with an unknown chemical and his eyes were burning. Officers reportedly found the victim, 61, with an orange substance in his hair and on his neck and shirt. He then told police that Williams, his next door neighbor, had made threats to kill him — allegedly picking up a stick during a heated exchange outside their homes. When interviewed by police Williams reportedly denied making any threats, but admitted to pepper spraying the neighbor, "to back him up." Subsequent questioning revealed Williams was upset over a fence post the victim had reportedly cut out of the ground along their shared property line, believing the pole to be his. Police say Williams demanded that the neighbor place the pole back in the ground, but he refused — keeping his foot over the hole during the confrontation. "Mr. Williams stated that (the victim) would not move his foot so he sprayed him with pepper spray," reads the officer's report. Williams was charged with aggravated assault and booked into the city jail, while pepper spray found at the scene was placed into evidence.
