A newborn girl, who was admitted to the district hospital after she was found buried alive, is in a critical condition, doctors said on Tuesday.

The police have registered a case against unidentified persons but are still trying to trace her parents, Senior Superintendent of Police Shailesh Pandey said.

The infant was rescued last Thursday by a trader who had gone to the cremation ground to bury his daughter, who died minutes after being born prematurely.

The newborn was buried in an earthen pot almost three feet below the ground.

Hitesh Kumar Sirohi, the trader, fed her milk using cotton and admitted her to the district hospital. 

The details of the girl's parents, who had attempted to bury her alive were yet to be ascertained, Superintendent of Police (City) Abhinandan Singh said.

"As of now, her life has been saved. We are trying to trace the girl's mother," he added.

Meanwhile, Chief Medical Officer (CMO) of Bareilly Vineet Shukla told PTI that Bithari Chainpur MLA Rajesh Mishra had taken the responsibility for the girl's treatment.

Senior Superintendent of Police Shailendra Pandey said a probe was launched to ascertain who had buried the infant alive.
