Detectives from the Ballarat Crime Investigation unit understand a 19-year-old woman was driving along Humffray Street South when she pulled over to the side of the road to allow a light-coloured sedan to pass by as it had been following her.

Instead of continuing up the road, the car parked in front of her.

A male and two females then jumped from their sedan and forced the woman into the boot.

The victim was driven around in the boot of the car for about 10 minutes before the car was stopped a short distance from where the ordeal commenced.

The incident occurred not far from the Redan Wetlands, near the Yarrowee River.
