Sri Lanka Police said that the explosion that took place behind a house in Elpitiya on Thursday (3) was caused by an accidental disposal of explosives into a fire set up to destroy garbage.
The Elpitiya Police had conducted an investigation following the report of an explosion behind the house in its jurisdiction.
Investigation revealed that a man who was engaged in the textile business was collecting waste material along with a servant and was setting the waste on fire.
