The girl's mother used to leave her in a locked room before going to work in a private hospital and the child spent about 10 hours there alone for about six months.
The CWC rescued the girl last night from the locked house in Mancheswar area here and refused to hand her over to her parents, CWC member Benudhar Senapati said.
Terming the confinement of the child as an "inhuman act", he said the parents have to ensure the safety and security of the girl before taking her back.
"I have told them (CWC) that the incident would not be repeated and we will arrange someone to look after the child. However, they did not agree to return the child," Das said, adding, a mother cannot torture her baby.
Senapati said, "We are not satisfied with that proposal of the parents. The child may be handed over to the parents if the CWC is satisfied with their proposal."
With the permission of the Additional District Magistrate, Khurda, CWC members rescued the girl after breaking open the lock of the room from the house last night.
