After looking under the bonnet, the pair walked to the back of the car, where the man allegedly attacked the woman.

"I walked to the back of the car to shut the back of the door, I had it open," the victim, who remained anonymous, told Nine News.

"He's grabbed the back of my head and slammed it into the back of my car and then I've just blacked out from that."

The woman said she didn't know how long she was unconscious, but told Nine News when she woke her clothes were ripped, her pants pulled down and the man was on top of her.

"I 'came to' once and he was over top of me and he's hit me across the side of the face. I've gone back unconscious (and) when I 'came to' (again) he was gone and all I thought was 'I just need to get home'.

"I want him to be put away. I don't want him to be able to hurt someone else."

The incident happened on Rose St, in the vicinity of the Warwick Golf Club.

The woman was taken to hospital for non-life threatening injuries.

Police said the man fled in his vehicle - a white single cab utility with silver tray back and sides.

Warwick Detective Sergeant Darren Tamblyn described it as a "brazen attack".

"It's fairly brazen, obviously there was still a bit of light around and it's on a road that is regularly travelled up to the Warwick Golf Club," Sgt Tamblyn told Warwick Daily News.

"This person seems to have taken advantage of the situation, she's obviously got the bonnet up of the car, he's seen that and stopped to offer assistance."
