A one-and-half-year-old boy fell into a 20-foot-deep pit dug by the Electricity Department at Chkuma here on Sunday evening.
The pit was dug for some earthing work.
Besides a rescue team, fire, medical and police personnel have reached the spot. Oxygen is being supplied through a pipe to the child, identified as Sachin, Chief Medical Office Parveen Garg said.
A CCTV camera has been lowered into the pit, which showed the child was conscious, he said.
The incident comes six days after rescuers pulled out four-year-old Mahi dead from a 70-foot-deep borewell near Manesar, where she was trapped for four days.
