At least six people sustained injuries when bombs, produced in a trial as evidence, exploded in a courtroom in northeastern Noakhali on Sunday.
"The explosions occurred as the bombs were not fully defused," a senior police officer told PTI over the telephone.
A police officer, showing the evidence to the court, got his hands burnt while five lawyers suffered minor injuries. The judge was not hurt and he immediately adjourned the court.
Though none of the six suffered serious injuries, Sub Inspector Ilias Ali said smoke engulfed the courtroom creating panic.
