Call for Melbourne sex assault witnesses

Images of two men who spoke to a woman before she was allegedly abducted and raped in Melbourne, have been released by police.

The duo are not believed to have been involved but could have useful information about the June 17 incident at Carlton.

Two other men, 26-year-old Harley Jarthur Palise and Jarrod Vincent Thomas, 23, were last month charged with rape, unlawful imprisonment and assault after allegedly picking up the woman in a car.

The two witnesses who are thought to have spoken to the alleged victim are described as aged between 20 and 30 and of Indian and Caucasian appearance respectively.

A third man caught on CCTV walking past a Grattan Street shop around the time of the incident is being urged to come forward too. He is also not a suspect.

The man is aged between 50 and 60, is partially bald and spoke with an accent thought to be Serbian, police said.
