Police have charged a man with an alleged double murder after a pregnant woman and her partner were found dead in Melbourne with the father-to-be's head severed and gruesomely mounted on a spike.
Athena Georgopoulos, 39, was allegedly killed alongside her 50-year-old partner, Andrew Gunn, at their Mount Waverley home in Melbourne's south-east just before 10pm on Monday night.
Heavily armed police swarmed the Adrienne Crescent property at 9.55pm after a neighbour heard screams and called triple-0.
Inside the small unit, officers allegedly found Mr Gunn's mutilated body next to the body of Ms Georgopoulos. The pair have yet to be formally identified.
A 34-year-old homeless man with two large dogs was arrested just hours later at nearby Westall train station, about 6km from the crime scene, at around 1.40am on Tuesday. He has since been charged with two counts of murder.
