Ramasamy and his two sons climbed down the well, which had little water, which was being pumped out with a diesel-run motor. As thick smoke billowed in the well, they suffocated, sought for help and fell unconscious, police said.
Noticing this, three persons got down to rescue them,but they too fell unconscious,after which villagers requisitioned the help of fire and rescue personnel.
Even before the arrival of fire force, the villagers brought them up, but by then Ramasamy had died, police said.
