Efforts are on to rescue a man who has fallen into a 40-foot-deep borewell at a Delhi Jal Board treatment plant in Keshopur Mandi area late last night. Four engines of the Delhi Fire Services are at the spot while the National Disaster Response Force (NDRF) leads the rescue operation. NDRF has failed to get any breakthrough using torches, lights, and cameras, and is now digging another borewell parallel to the one in which the child has fallen. The authorities have brought in an excavator for this purpose.
