Police have identified several suspects believed to be behind nine suspicious blazes lit during the height of Victoria's fire emergency.
At least 14 grass and scrub fires are being probed by arson squad detectives, who have so far found nine of those fires were deliberately lit.
The fires were started across the state on Sunday, from along the Great Ocean Road to near Bendigo, in the Latrobe Valley and in two spots in the Merri Creek in Melbourne's northern suburbs.
Chief Commissioner Ken Lay says police have suspects in a number of these fires.
"It is just so lucky that we haven't got people who have lost their lives or been seriously injured as a result of these actions," he said.
The cause of the five other fires being probed by police are not yet determined.
One of those fires, near Bendigo, burnt about seven hectares of grassland after starting about 500 metres north of the Calder Highway.
Police are trying to find a man seen in a dark blue BMW who had been telling everyone about the blaze.
He may know more about how it started, police say.
