A four-year-old girl fell into a 70-feet deep borewell in Kho village near Manesar while playing with her friends on Wednesday night.
The Army has been called to assist in the rescue operation, officials said.
"Mahi was celebrating her fourth birthday and was playing with children outside the home near the borewell when she suddenly fell into it," her father Neeraj said.
Parallel to the borewell, a large pit is being dug to rescue the child. Chief medical officer Praveen Garg said oxygen is being pumped in the borewell to help the child. A camera was also lowered into the borewell to find out the condition of the child but it did not provide any significant detail.
