Rescuers on Sunday managed to reach four-year-old Mahi, 82 hours after she fell into a 70-feet-deep borewell near Manesar.
On Saturday night they had managed to pierce a hard rock-- a major hurdle which the rescuers had been struggling to break for the last two days.
Rescuers have managed to reach the girl and efforts are being made to take her out, an official said.
The girl Mahi fell into the borewell at Kho village near Manesar while playing with her friends on June 20, her fourth birthday.
Oxygen is being constantly supplied to Mahi since the rescue operation began.
Over 100 officials drawn from army, fire, police, Gurgaon Rapid Metrorail, health and revenue departments, and locals have been involved in drilling a pit parallel to the borewell.
