The police have spokes to the family and asked the father to submit in writing that he'll ensure her safety.
For eight years, residents of Pura Amar Singh village in Uttar Pradesh's Agra district and neighbouring hamlets have considered 15-year-old Neeru Singh a "goddess".
When she was six, her fast had "led to rain in the parched village", they say.
After the incident, her fame spread and a temple was also built in the village at her instructions, the villagers say.
Her father and other villagers then began to hold a community festival in her name. According to villagers, she stopped eating and has been surviving on liquids ever since.
Attired in red and adorned with heavy jewellery, she bore a striking resemblance to controversial self-styled godwoman Radhe Maa.
On September 21 this year, as news of the girl "taking samadhi", or leaving her body as a form of mediation spread, thousands of people from nearby villages gathered in Pura Amar Singh and started chanting bhajans to please the "goddess".
Women in large numbers started worshipping the girl.
With the crowds swelling, area police officer Karamveer Singh reached the spot and intervened. The girl was shifted to her residence from the temple where she was placed under house arrest.
The police then spoke to the family and asked the father to submit in writing that he'll ensure her safety. To control the crowds and prevent any unrest, policemen have been deployed in the area.
A team of doctors from the health department also reached the village and examined the girl after the administration was informed that she has been on a liquid diet for the past many years.
Tehsildar Kumar Sanjay said, "He (the father) seems to have provoked her to take this extreme step. It seems that the girl's father is earning money by claiming that she is a goddess. Police are doing their investigation after which action will be taken against him."
Finally on Monday after efforts by the police and authorities, Neeru Singh gave up her red saree and jewellery, and returned to the classroom.
