Chennai, Oct 27 (IANS): Rescue efforts continued for the third day on Sunday to save a two-year-old boy who fell into an abandoned borewell in a village in Tamil Nadu's Tiruchirappalli district.

The boy fell into the borewell at about 5.30 p.m. on Friday and got stuck at 30 feet. Later, he went further down and got stuck at about 100 feet.

Presently an ONGC rig has been deployed to dig a hole near the borewell into which firemen would go down and reach out to the boy burrowing a tunnel inside.

On Saturday, the National Disaster Response Force (NDRF) and State Disaster Response Force (SDRF) took over the rescue operations as other techniques used to take the boy out of the borewell failed.

Initially, earthmoving equipment were pressed into service to dig a pit near the borewell to reach the boy. But it was stopped midway as the terrain was rocky.

Breaking it would result in vibrations that may loosen the soil inside the borewell, thereby slipping the boy further down.

Later, the rescue team used a special equipment 'borewell robot'. But that too was not successful.
