About 38 people were killed when mobs attacked Christian settlements in Kandhamal in 2008, following the murder of Vishwa Hindu Parishad leader Swami Lakshmananda Saraswati and four others. Hundreds of houses and dozens of places of worship were set ablaze during the riots.
The police said a group of people had attacked the under-construction structure on Thursday and two persons have been arrested in connection with the incident, while a manhunt was on for others. The police were also mediating a settlement between the two communities.
According to a complaint made by the community leaders, the accused persons threatened 15 persons of eight families involved in the construction work of the prayer house.
All the 15 persons met the SP Kunor Bilash Singh on Friday and apprised him of the situation, who further gave directives for necessary action against those involved.
