A division bench of the High Court comprising Justice Sharifuddin Chaklader and Justice AFM Ali Asgar also discharged the rule earlier issued by the court upon the government.

The High Court, in its observation, said as the case is in the trail court, it has no jurisdiction to order for further investigation into the case.

"The trial court, if it feels necessary, can reinvestigate the case," it observed.

Former finance minister and Awami League lawmaker SAMS Kibria and four local leaders of the party were killed in a grenade attack on a rally in Habiganj on January 27.

On March 20, Senior ASP of the CID, Munshi Atiqur Rahman, submitted the charge sheet to the court against 10 people.

The complainant, Abdul Majid, organising secretary of Habiganj Awami League, had alleged that the CID submitted the charge sheet to the court ignoring him.

Majid had lodged a revision petition with the District Judge's Court, Habiganj, on May 4 for reinvestigation into the case. The district judge discharged the petition.

Abdul Mazid then filed a writ petition with the High Court challenging the order of the district judge and seeking cancellation of the charge sheet and a direction for further investigation into the case.

Dr Kamal Hossain and Advocate Mahbubey Alam moved for the petitioner.
