The New York Times and AFP reported on a police chief warning security officials in an advisory ten days before the attacks of a threat to prominent churches from a radical Islamist group, National Thowheeth Jama'ath. No information in this regard had been passed to the senior politicians of the country; Minister Harin Fernando then tweeted images of an internal memo and report by the police intelligence of a terror attack planned by the founder of National Thowheeth Jama’ath, Mohammed Zahran.
