SASARAM: A vast stretch of the recently laid National Highway (NH)-2C bulged, cracked and created an explosion-like sound at Chitauli village under the Tilothu police station area, about 40km from here, on Friday.
Locals said a shrilling sound, like the one that accompanies a high-intensity explosion, was heard in a radius of 6km from the spot where the road stretch developed a massive crack. "We initially mistook it for a Maoist operation as the region is a stronghold of Left extremists," said a villager.
