Whoever fired shots into three Melbourne pizzerias owned by the same family may have been trying to send a message, police say.
Police say there's nothing to suggest the shootings are connected to bikie gangs.
The three Woodstock Pizza restaurants - one of which is under construction - were sprayed with bullets about an hour apart overnight.
The first shots were fired into the side window of the North Fitzroy restaurant about 11pm (AEDT) on Wednesday.
Shots were then fired into the vacant building in Essendon, and a third restaurant in Brunswick East.
Neither of the operating restaurants were open at the time.
Detective Inspector Adrian Dalzotto said police could not overlook the possibility a message was being sent to the owner.
"Whatever it is, we can't overlook the coincidence that there's three premises all run by the one business," he said.
"Whatever it is, the motive and message and whatever, we've still got to work through that."
Det Insp Dalzotto said at this stage, there was nothing to suggest it was linked to bikie gangs.
"Any shooting, any violent incident, we're going to look at everything, that will be part of our inquiries," he said.
"There's nothing to suggest that it is, but it's just a matter of course for all our investigations, we'll follow a particular line and just cancel out any possibilities in that regard or any other area of crime."
He said the shootings may have been planned for after the restaurants were closed, but it was lucky no one was injured.
"They're in areas where, down there in Fitzroy and Brunswick, you could have had anybody down there," he said.
