Perry Kouroumblis, a dual Australian-Greek citizen, has been extradited from Italy to face charges in an almost 50-year-old cold case known as the "Easey Street" murders.

Kouroumblis has been accused of killing two women in 1977, with one victim being raped.

The bodies of Suzanne Armstrong and Susan Bartlett were found with multiple stab wounds in their Melbourne home.

Victoria Police have been investigating the case for decades, offering a reward for information.

Kouroumblis was arrested after moving to Greece and will now face charges of murder and rape in an Australian court.
