Victoria Police are investigating a second shooting in Melbourne's Roxburgh Park.
Two teenagers are recovering in hospital after their legs were peppered with bullets in what Melbourne police believe is the latest chapter in a war between rival Middle Eastern gangs.
The pair, aged 16 and 18, were shot and another two men were bashed early on Friday morning at Roxburgh Park.
Police do not believe the latest shootings are linked to Wednesday's killing in the same northern suburb where a man was shot dead.
The teens were hit with a number of bullets at 2.30 am, and they were taken to hospital in a stable condition with non-life threatening injuries.
A hospital spokeswoman on Friday said the pair remain stable.
The bashing victims, two 20-year-old men, were found with "blunt force trauma" injuries, with one taken to hospital and the other refusing treatment.
Detective acting Inspector Mark Burnett said the two groups of men met in the street and fought before the shots were fired.
"The victims are not cooperating with police due to their perceived fears of possible retribution," he told reporters.
"We believe that in relation to this incident, there's Middle Eastern factions involved but we're keeping an open mind as we progress with the investigation."
It's believed to be a targeted attack but is unrelated to the fatal shooting on Wednesday just three kilometres away, Insp Burnett said.
A 21-year-old man, named in media reports as Anwar Teriaki, was shot dead in Coronet Ave at Roxburgh Park at 12.30 am on Wednesday.
The spate of recent shootings has left Roxburgh Park residents fearful.
"I'm frightened for my family ... I'm actually shocked there's another shooting," a witness told Seven News on Friday.
The police presence in the suburb is being beefed up, with mounted police spotted patrolling the streets on Friday.
