CLERMONT COUNTY, Ohio — A man who has worked as a police officer in several departments in the Greater Cincinnati area now faces multiple allegations of having sexual contact with a minor.

According to a news release from Clermont County Prosecutor Mark Tekulve, Robert Ellison, 36, was charged with three counts of gross sexual imposition. He pleaded not guilty to all three in court Wednesday.

Tekulve said if Ellison is convicted of all charges, he could face up to 15 years in prison.

Most recently, Ellison was employed by the Elmwood Place Police Department; However, the charges stem from crimes allegedly committed while he was an officer with the Williamsburg Police Department in Clermont County, Tekulve said.

Elmwood Place Police Chief Randall Newsome told WCPO that Ellison was employed by his department for only two weeks, before resigning a week ago “for personal reasons.”

According to Tekulve, in addition to working as a police officer in Elmwood Place and Williamsburg, Ellison recently worked as an officer with the Camden Police Department, the Preble County Sheriff’s Office and the Owensville Police Department.

In court, prosecutors said Ellison, while in costume during a live-action role-playing (LARP) practice, cornered the victim, who was sitting inside a vehicle waiting for her parents. Ellison then intimidated, kissed and forcibly touched the minor, prosecutors said.

The case is being investigated by the Ohio Bureau of Criminal Investigation. Prosecutors said in court that BCI “continues to receive reports of alleged misconduct by Ellison.”

In court Wednesday morning, Judge Kevin Miles ordered Ellison held on $100,000 bail. Ellison is due back in court on November 14.

BCI is asking anyone who may have had a questionable interaction with Ellison to contact deputies at 855.224.6446.
