But Mike McCoy, the chief of the police department in the Columbus-area village of Mount Sterling, said his resignation was unrelated to the incident, in which one of his officers shocked the boy twice with a Taser, The Columbus Dispatch reported.
McCoy was placed on paid leave last week after he failed to tell Mount Sterling Mayor Charlie Neff of the Taser incident.
McCoy said a shrinking budget prevents him from doing his job.
Neff said lawyers are working on a separation agreement and the village council would formally accept McCoy's resignation from the $49,900-a-year job at its meeting in two weeks.
The entire part-time police force in the village has been disbanded for now and the Madison County sheriff's office will patrol the village. The Dispatch said there was no discussion of hiring a new chief or bringing back officers.
Police said the 9-year-old, Jared Perry, was shocked with a Taser twice by Officer Scott O'Neil, who came to the boy's house over his truancy last Tuesday morning.
A police report said Jared -- who weighs 200-250 pounds and stands 5-foot-5 to 5-foot-8 -- refused to cooperate with the officer and resisted arrest.
The report said after being shocked once, Jared still did not cooperate and was shocked a second time. An ambulance was called but he had no sign of injury, the Dispatch said.
