A uniformed Summit County sheriff's deputy is accused of stopping a woman on an Akron street and sexually assaulting her in a parking lot.

Deputy Antonio Williamson, 46, is accused by prosecutors of rape, kidnapping, sexual battery and gross sexual imposition.

Williamson voluntarily surrendered to Akron police detectives Thursday morning and was then booked into the Stark County Jail pending an initial court appearance.

The alleged assault took place around midnight on March 19 in Akron. Investigators say Williamson had just ended a secondary job and was still in uniform and driving a sheriff's cruiser when he approached the 26-year-old woman as she walked near Romig Road.

The attack took place in a parking lot, a police report shows. The Munroe Falls woman was treated for injuries afterward at Akron General Medical Center. She had never met Williamson prior to the encounter, authorities said.

Akron police conducted the investigation and Summit County prosecutors announced the indictment Thursday. He will be arraigned Friday.

An attorney for Williamson could not be immediately determined.
