Need help. Illegal body cremation near my friend’s house.

A close friend of mine from Mangalore constructed a house in a layout in Mysore’s newly developed areas (6 km from the Bogadi signal). It’s been three years since he constructed the house, and everything was running fine, but there’s a village behind his layout, and for the last one year, those villagers have been cremating the body inside the layout. When he inquired, he came to know that there are two castes in that village, and one caste is not allowing the other caste to access the public cremation ground, which is around 8 km away from the layout. So these people decided to burn the dead inside the layout. What to do, and whom should he complain to?
