The mother of the two-year-old battered baby has been traced and will undergo a DNA test to ascertain whether she is the biological mother of the child.
A senior police official said they traced the mother named Munni last night and she is being brought to Delhi.
Munni has allegedly left her daughter, Falak with one Laxmi in September last year.
Falak has been battling for life at the AIIMS hospital, were she was brought on January 18 with severe head injury, both her arms broken, bite marks all over her body and her cheeks branded with hot iron.
The teenage girl, who brought her there claiming to be her mother, had cited a fall from the bed as the reason for the child's pathetic state.
Falak has already undergone two life saving surgeries till now.
