Jharkhand state has nearly the double national average of Christians, with around 4.5% being believers. The majority of them are from local tribes or the untouchable castes, making them a generally very poor section of society.
The state is completely governed by Prime Minister Narendra Modi's BJP Hindu nationalist Party, which has been accused of failing to adequately address hatred and attacks against Christians, and even encouraging them.
Various protests have occurred across India since Narendra Modi came to power after attacks on churches and believers, one of which includes the gang-rape of an elderly nun at her convent.
Mr Modi has publicly defended religious freedom and condemned attacks on Christians.
Subhash Khongar, a lawyer and district president of Indian's national Christian forum the Rashtriya Isai Mahasangh, said: "Every year we witness an average of two murders in the area and several other forms of violence.
"They are all part of an agenda to terrorise people [so that they] disassociate with Christianity."
