A woman was arrested in Pune for allegedly posing as a nurse and kidnapping a three-month-old girl from a hospital here, police said on Friday.

The woman, identified as Vandana Jethe (24), was moving in the corridors of Sassoon General Hospital here on Thursday wearing a white apron, the kind worn by nurses, and approached a 22-year-old woman who had come there with an infant in her arms, an official said.
