"The truck fell into the canal in Abushehr village. The driver may have dozed off or lost balance over the vehicle," Deputy Superintendent of Police, Dabwali, Satya Pal said.
There was no immediate confirmation as to how many were on board the ill-fated vehicle.
Asked about estimate of the number of people in the truck, Pal said, "We cannot make a guess till the time we locate the truck and fish out any bodies or trace out any survivor."
