At approximately 1.20pm that day, a man was also approached on Haverstock Rd, in Sandringham by three unknown males – one of whom was carrying a hockey stick - and assaulted by two of the men.
Around the same time, another man reported that a group of males in a silver vehicle approached him on Locarno Ave, and punched him multiple times before decamping in a silver vehicle.
Franich said police believe these incidents are connected, but not racially motivated.
"After speaking with all three victims police are satisfied that race was not the motivation behind these incidents," he said.
"We believe these attacks were random in nature, where the offenders targeted people who were isolated and on their own.
"We want to hear from anyone who witnessed any of these incidents or saw a silver Subaru station wagon in the Sandringham or Epsom areas on June 3 and came into any contact with its occupants."
Last week, one of the victims told the Herald he was walking through Sandringham on Monday when he was violently attacked by three men.
"As I crossed the pedestrian crossing a car with young guys in it tried to hit me," said the man, who did not want his name published.
"They were going about 50-60km/h … they drove at me, I think their intention was to hit or scare me.
"I tried to ignore them and get across the road, I just thought they were immature."
He walked down Fowlds Ave and into Locarno Ave.
"Then I realised they had followed me … they got out of the car, three guys, and they started punching me," the victim recalled.
"They were beating me all over - my head, neck, stomach, chest, all parts of my body.
"I started screaming for help … after 10 to 20 seconds they did what they had wanted to do.
"As they were going back to the car they yelled some words at me - bad words, it was racist and I would not even be able to speak the words or tell you because they were terrible."
The attackers drove off and the man, after clocking the car's registration number, made his way home to call the police.
His wife was horrified and he was still in shock.
"I am thankful that I am fine, that I am home," he said.
"I have some pain in my body but it is bearable … it could have been much worse."
