Four people have been found dead at a home in Melbourne's northwest.
Victoria Police confirmed the incident to Yahoo News Australia on Thursday afternoon.
A man is assisting homicide detectives, while a crime scene has been set up at the Tullamarine property.
Police say there is no ongoing threat to the community.
"The exact circumstances around the incident are under investigation and we will provide more information when it's appropriate to do so," a spokeswoman said.
The Herald Sun understands two primary school-aged girls and a boy lived at the home with their mum.
Neighbour John Constantino told the paper the “friendly” mum adored her kids who “were always dressed nice”.
“No one around here would say a bad thing about her,” he told the paper.
