Armed Crime Squad detectives are now investigating the shooting.
It comes as the city reels from a spike in gun crime with twice as many people shot dead in Melbourne last year.
Earlier this month an Age investigation revealed that 52 people were shot and 14 fatally gunned down across the state in 2019, twice as many as the previous 12 months, with handguns increasingly used by criminals to settle drug debts or underworld disputes.
While data showed the most common place to receive non-fatal gunshot wounds was the hip and knee area, 15.4 per cent of victims were shot in the upper body and 17.3 per cent to the head.
Already this year, at least seven people have been shot, one fatally, in a string of public shootings that include the unsolved daylight killing of underworld identity Nabil Maghnie on a busy Epping street in January.
Other 2020 shootings include a February 8 attack on a kebab shop owner at Sunbury that left grandfather Yusuf Kucukbas with a wound to the leg.
A week later Machar Machar, 19, was shot in the hand at the rear of Chapel Street nightspot Chasers in South Yarra.
Then, on March 7, aspiring hip hop artist Kevin Passanise, 25, was critically injured when he was shot in the upper body while parked in a driveway in Shrives Road, Narre Warren South.
