A 22-year-old woman allegedly killed her infant daughter at Ranala village near Nagpur on Thursday, the police said.

The accused was identified as Payal Anil Kanoje, resident of Aroli in Mouda tehsil of Nagpur district.

An official said Payal had given birth to the baby 23 days ago in a premature delivery.

The family, which is very poor, had arrived in Kamptee on Wednesday for the child's treatment at a clinic.

Around 2.30 am on Thursday, Payal allegedly strangled the baby, and placed the body in a heap of manure outside the house, the police officer said.

Sometime later she raised an alarm that the child was missing.

The family approached the Kamptee police station and registered a complaint, but Payal later confessed to have killed the girl, the officer said.

Police said she was reportedly tired of the baby's crying, her health issues, and the financial strain that the premature birth had put on the family. Further probe is on.
