A few years ago, a quarry was run at the land, but the Central Environmental Authority cancelled its license following complaints.
A person by the name K. Sasikumar has bought a 10-perch block from the land and is removing sand from the land.
After the rock surfaced, boring has been done improperly to remove it.
The owner has threatened the 10 families living nearby with death after they took up the matter with him.
Owner Sasikumar said he has done the boring with CEA permission.
