Investigator Babul Mia, an inspector of the police’s Criminal Investigation Department, submitted the chargesheet to a Narayanganj court on Thursday after about three months of investigation.
Preparations are under way to file a supplementary chargesheet against another eight people. The police needed permission to charge these eight people because they are government officials, said Nasir Uddin Ahmed, a special superintendent of police at the CID.
More than 50 Muslim worshippers sustained burn injuries when six air conditioners at a mosque in Narayanganj’s Fatullah exploded on Sep 4 during Isha prayers. As many as 34 of the critically injured people died after being hospitalised. Only four victims survived the blast.
The fire service personnel later confirmed that gas accumulated inside the mosque from pipeline leaks caused the blast triggered by an electric short-circuit.
The police arrested 12 people and all of them secured bail. Besides mosque committee President Abdul Gafur Mia, the arrestees included engineers of Titas and electricians of Dhaka Power Distribution Company.
