Victorian police are investigating a strange case of why a woman was trapped under a derelict Melbourne house for four days.
The woman, aged in her 40s, was freed from under the run-down Essendon house on Miller St on Saturday night, the Metropolitan Fire Brigade said.
It's believed she crawled underneath and became trapped but police have not yet confirmed the story.
The woman was discovered by a relative of the homeowner who heard scratching beneath the wooden floorboards of the house and called for help.
Firefighters said it was a "strange situation" and they launched an "intricate rescue plan" after they were called to the home about 7pm.
