Mourning the death, the girl's father said that the police had not taken action against the culprit who had used his influence to harass his daughter.
"I had complained to the police. If they had acted then, my daughter would not have had to suffer so much pain. I am a weak man, and the culprit is powerful. Also, I am a poor man, and my tea stall is all I have to sustain my children with," said the victim's father.
Uttar Pradesh's Chief Minister Akhilesh Yadav said that the government would punish any officials found guilty of failing their duty.
