The family targeted in a series of shootings at Melbourne pizza restaurants have no idea why they are being attacked, police say.
Bullets have been fired into three restaurants in the family-run Woodstock pizza chain in four late-night attacks over the past four months.
Police say there's no evidence of underworld involvement and no suggestion a rival pizza restaurant is linked to the shootings.
Bullets were sprayed through the window of the Cannata family's restaurants in Fitzroy North, Essendon and Brunswick East on October 30 last year around midnight when the restaurants were closed.
CCTV footage show a white Ford Falcon sedan and a silver Toyota Hilux were used in those shootings.
The latest attack saw the closed Essendon store targeted on February 3.
Security cameras captured two people firing three times into the closed restaurant's front window around 11.50pm and fleeing the scene on foot.
Detective Sergeant Paul Topham said whatever message the perpetrators were trying to send was lost on the owners.
"They're terrified. They don't understand why they've been targeted. They don't know when it's going to stop. They just want to be able to go to work in peace," he told reporters on Saturday.
"They haven't received anything (communication) and they don't understand why it's happening.
"At this stage they don't have any idea why they've been targeted."
"We've spoken to our victim and there's nothing to suggest any other pizza chain is involved in this incident.
"There is no credible information at hand to suggest there is any underworld or gangland-type involvement, nor is there any outlaw motorcycle gang involvement."
Three generations of the Cannatas are involved in the restaurants in Melbourne's northwest.
Their first restaurant was opened on Nicholson Street in Fitzroy North more than 20 years ago.
The Essendon store was under construction when it was shot at in October.
No one has been injured in the shootings, but Det Sgt Topham said police feared they could continue.
"It's a dangerous circumstance when you have people prepared to go out in a public area and discharge a firearm with absolutely no regard for the people living in the area."
