Lake County detectives arrested a deputy sheriff Wednesday evening on charges of sexual battery after a woman accused him of raping her on New Year's Day during an encounter with her and her boyfriend.

According to Lake County Sheriff Spokesman John Herrell, the woman filed a complaint against Deputy Sheriff Matthew Donnelly later the same day.

According to her account, she and her boyfriend had been out celebrating New Year's Eve at a bar in Orlando. At some point, she said, she passed out after drinking too much. When she awoke, she said, she found Donnelly standing beside the car, which was in a parking lot of a closed business along Highway 27 in Minneola.

According to the Sheriff's Office, Donnelly put the woman's boyfriend in the back seat of his patrol car. Then, the woman said, Donnelly began to grope her and make inappropriate comments as he told her he would not take her boyfriend to jail.

She said she was frightened and felt as though she had no choice but to cooperate with the officer. Donnelly, she said, told her not to tell anyone about what was taking place.

The report released late Wednesday stated that Donnelly eventually called for a relative to pick up the victim and her boyfriend. The victim then told the relative about the incident, and the relative contacted detectives.

Herrell stated that a sexual assault examination was performed on the victim and evidence supported her claim.

When reviewing the dash-camera video from the patrol car, Herrell said, detectives found that it had been turned off for about 22 minutes.

Donnelly's patrol car was processed for evidence, he said, and swabs were sent to the Florida Department of Law Enforcement's lab for analysis. The analysis showed that the victim's DNA was found on the steering wheel, the gear shifter knob, and the flashlight in Donnelly's patrol car.

Donnelly was booked into jail just after 8 p.m. Wednesday, and bond was set at $10,000.
