Steve Dimopoulos MP offered his sincerest sympathy to the family of this young man and said “no person should ever die in these circumstances.”

He took to social media to thank Victoria Police for “their timely response”.

“This is a location that is loved across Melbourne. It is on the map as a safe place for people to dine and come together,” Mr Dimopoulos said.

“There is no place for violence in our community. Not now. Not ever. Whatever disagreements people may have – it is never worth someone’s life.”
