The child had been kidnapped and raped near her house on April 17; her parents found her the next morning, bleeding and unconscious. She remained in a coma for over a week and died of a heart attack, said doctors.
"The man who did this to her should be hanged publicly," said her mother today, who broke down as she spoke to reporters.
The 35-year-old man who allegedly raped the child was arrested in Bihar last week. It took the police nearly a week to find him.
The details of the horrific assault in Madhya Pradesh emerged as the news of a five-year-old being kidnapped and raped triggered large protests in Delhi. That child is still in hospital where doctors say her condition has stabilized.

In December, the security of women became a national agenda when a young student was brutally gang-raped on a moving bus in Delhi. She died two weeks later.
