Dismissing the allegation by relatives of the victims that a group of 70 people attacked the three Indians, it said only four men were involved in the assault and a group of up to 20 were bystanders.
"Four men had been involved in the actual assault and a group of up to 20 had been bystanders," Acting Senior Sergeant Glenn Parker was quoted as saying by 'The Age'.
A Victoria Police spokeswoman said, "Police had witnessed about 15 men and women making racist comments and one woman was throwing water on a bystander during the heated incident."
Four men were arrested and interviewed in this connection but have been released for further investigations, police said.
26-year-old Sukhdip Singh, who arrived here a month ago on a spouse visa, his brother Gurdeep Singh and uncle Mukhtair Singh were attacked by a group of Australians.
