At least 12 shots were fired into Platinum Athletic Fitness on Whiteman St in the early hours of this morning, penetrating a large window and roller doors and smashing mirrors inside the centre.
It’s believed the renovated warehouse was hit sometime before the gym doors opened at 5.30am.
Police do not know the motive for the shooting or whether it was linked to similar incidents across the suburb.
Platinum Athletic Fitness owner Shane Reeves, who opened the centre a month ago with his wife, said he couldn’t understand why someone would target the gym.
“We’re here to serve the community, these senseless acts of violence don’t serve anyone,” he said.
“We’re trying to create a community that’s safe for our kids and our families yet people are willing to stoop to these lows to get their message across, whatever that message is.
“My message to them is the community is stronger than a single act of violence…we’ll show these people we’re here for the long haul.”
Detective Senior Constable Adam Burnett said it was believed the weapon involved was either a rifle or a hand gun.
It was lucky no one was inside at the time, Sen-Constable Burnett said.
Detectives are photographing the area and will check CCTV from nearby businesses.
The gym had not yet installed security cameras after opening a month ago.
The owners said they would be boosting security measures in the wake of this morning’s event.
Port Phillip Crime Investigation Unit detectives are investigating the shooting.
Anyone with information about the incident is urged to contact Crime Stoppers on 1800 333 000.
