At about 9:40 am on 8 December 2005, a bomb was discovered in front of the offices of Bangladesh Udichi Shilpigoshthi, a secular cultural organisation.
[4][5] Among the fatalities were two officials of the Netrokona district Udichi: joint convenor Khaja Haider Hossain and organising secretary Sudipta Paul Shelly.
On the day of the bombing, State Minister for Home Affairs Lutfozzaman Babar blamed the attack on a Hindu man, Yadav Das, who was killed by the explosion.
[8] A week after the bombing, Babar rescinded his premature statement and said the investigation found that Das was innocent.
[15] The district unit of the Awami League, then in opposition, called a daylong hartal (strike) on 10 December to protest the attack.
[17] The Supreme Court Bar Association visited the surviving victims on 18 December 2005 and called for the government to provide compensation.
