Between 1am and 2am on Sunday 12 April 2015, the 33-year-old woman was walking on Worsley Road from the direction of Liverpool Road when a car stopped and the driver offered her a lift.
She got into the car before it stopped on Hall Bank.
She was told to get out before she was raped on Bridgewater canal tow path.
The man then drove off.
