Officers said they “are not looking for anyone further at this early stage.”
“The exact circumstances are yet to be determined at this stage. The area has been cordoned off,” police said.
“Anyone with information or who witnessed the incident is asked to go to Melbourne West Police Station to make a statement. We will provide further information when it comes to hand”
The apparent attack came as a 28-year-old James Gargasoulas underwent trial in Melbourne for driving into a crowd in the same area in 2017, killing six people.
