Police found the corpse of a 34-week foetus wrapped in a plastic bag inside a wardrobe at a Peruvian couple's apartment in the northwest Italian city of Turin on Tuesday.
Police made the grim discovery in the couple's bedroom after receiving a call from doctors at a hospital where the 36-year-old woman was admitted suffering severe bleeding from her womb.
An autopsy was due to be carried out on the infant to establish the cause of death.
The couple have two children aged five and seven.
Prosecutors have opened a probe into the baby's death.
