CCTV vision from just prior to the explosion shows a man wearing backpack making his way through crowds outside of the church.
Indian channel TV9 reports the man is one of the suicide bombers, who are suspected to be a part of the extremist Muslim group National Thowheed Jamath.
Links to other groups, like Islamic State and Al-Qaeda, have not been ruled out by local authorities.
The series of explosions happened across the country, with several hotels - the Shangri-La, the Kingsbury, the Cinnamon Grand and the Tropical Inn - targeted.
The manager of the Cinnamon Grand hotel in Colombo told AFP that one of the alleged suicide bombers checked into the hotel the night before the attack and detonated the blast as he was served breakfast.
Emergency powers have been invoked, allowing police and military to detain and interrogate suspects without court orders.
Among those killed in the blasts were three children of ASOS billionaire Anders Holch Povlsen.
