Central leaders of the Awami League accompanying Hasina along with local activists and journalists were all injured in the attack.
Moslem Uddin, the then general secretary of Kolaroa Awami League, later went to file a case over the incident at the Kolaroa police station but the law-enforcing agency refused to record it.
Moslem Uddin then filed a complaint with the Satkhira court on Sept 21, 2014, more than a decade after the attack. The court subsequently ordered the police to start a case on the basis of the complaint.
Police pressed formal charges against 50 people, including Habibul Islam Habib, a BNP MP at the time, following an investigation. In February, A Satkhira court sentenced accused to jail for varying terms.
