Since no offer of high positions or menace of threats could force Devasahayam Pillai to renounce his Christian faith, the King arrested Devasahayam on 23 February 1749. He was paraded to different places and cruelly tortured in public to make him give up his faith, to warn other Christians and to stop conversion.
After three years of tortures, and being thrice condemned to death, he was finally shot to death, on 14 January 1752, after an exemplary life of virtue, prayer, penance and mortifications, and the body was thrown into the forest to be eaten away by the wild beasts. His mortal remains were discovered by the Christians and buried in front of the main altar in the most important church of St.
Francis Xavier, which is the present Cathedral of the Diocese of Kottar. The Bishop of the diocese when he heard of the heroic death of the Servant of God, decreed that Te Deum be sung in all the churches in gratitude to God for “palm of martyrdom” obtained by Devasahayam Pillai.
