Four people are in hospital, one in a critical condition, after a frenzied stabbing attack in Melbourne.
Three underwent surgery and another is under police guard following the incident in Sunshine North on Thursday.
Police were called to a home just after 4pm where they found two women, aged in their 30s and 60s, and a man in his 30s with significant stab wounds.
Another man at the property, aged in his 20s, sustained injuries to his upper and lower body and is in a stable condition under police guard in The Alfred hospital on Friday.
"The investigation is in its early stages at the moment, but we want to reassure the public that it's been contained and there is nothing to worry about," Acting Inspector Cameron Reinke told reporters, adding they were all known to one another.
