A woman has been sexually assaulted by two men who convinced her to get into their car after they told her they were ride-share drivers.
The woman was out with friends in the Melbourne CBD on July 29 and was travelling around the city between 11pm and 3am.
She was walking and catching public transport throughout the night when she strolled past a car under the Queens Bridge about 3.30am.
Police believe she was then approached by two men who were in the vehicle.
"The men told the victim it was a ride-share vehicle and she has gotten into the car," a police spokeswoman said.
"The woman was then driven to Albert Park, where she was sexually assaulted."
In a bid to defend herself from her attackers, the woman punched one of the men in the face and was able to get out of the car and call police.
In the months since the attack, detectives have reviewed hours of CCTV footage to try and track the woman's movements through the city.
They were able to find images of a man they wish to speak to in relation to the attack.
He is believed to be a witness and is not thought to be involved in the assault, but is thought to have spoken to the to the victim earlier in the night.
Investigators have also released images of a silver, mid-2000s model Toyota Yaris hatch that is similar to the vehicle thought to be involved in the incident.
The two offenders have been described as of Indian or sub-continental appearance and aged between 25 and 35.
In Brisbane in September, a man was charged after he allegedly pretended to be an Uber driver before sexually assaulting two women in the inner-city.
