An Ohio sheriff's deputy has pleaded not guilty to charges for allegedly raping a 26-year-old woman inside his county-issued cruiser.

Summit County deputy Antonio Williamson entered pleas Friday during an arraignment in the county court in Akron. He was indicted Thursday on rape, kidnapping, sexual battery and gross sexual imposition charges.

His attorney declined to comment after the hearing. A judge set a $100,000 bond.

The 46-year-old Williamson supervised the sheriff's office crime scene unit. He surrendered to authorities Thursday.

Prosecutors say the sexual assault occurred outside an Akron gentlemen's club in March. A county prosecutor's spokesman has said Williamson was in uniform and was leaving an off-duty security job prior to the assault. The spokesman says Williamson didn't know the woman previously.
