Melbourne unit fire sparks evacuations

Residents of several apartments have been evacuated after a unit fire threatened to spread to neighbouring homes in Melbourne's northwest.

Multiple emergency calls were received before 8am on Monday and fire crews conducted "an aggressive attack" to stop the blaze spreading to other units at the Kings Park premises, the MFS said.

One occupant had been unaccounted for, but a search confirmed no one was home, and police are now trying to contact the owner.
