Four good Samaritans who stopped to help a woman who was being sexually assaulted on a Melbourne beach are sought as police try to identify the attacker.
Police say a 31-year-old woman was running along the foreshore on Beaconsfield Parade between Fraser Street and Langridge Street on Saturday night around 11pm to 11.30pm.
She was grabbed from behind by an unknown man and forced face down into the sand. She was then sexually assaulted.
A man and a woman came to the victim's aid, as did two men who were both wearing white shirts.
The attacker fled the scene. He was wearing a dark coloured, hooded jumper at the time.
He is described as Caucasian, 178 centimetres tall, medium build with light-coloured eyes and light-coloured hair.
A digital likeness of the man has been released.
Detectives want to speak to the three men and the woman who came to the victim's aid, or any witnesses in the area at the time of the incident.
An information caravan will be set up on Beaconsfield Parade opposite Fraser Street from 5pm to 9pm on Thursday.
