Although two days have elapsed since the horrific blasts at a mosque in Narayanganj, it is yet to be unearthed what actually caused the explosions that killed 24 people and injured many more.
Fire Service officials said gas accumulated inside the mosque from a leaked pipeline might be the reason behind the explosions.
However, investigations are underway as different probe bodies have been formed to unearth the reason.
On Saturday Titas Gas Transmission and Distribution Company Ltd formed a 5-member committee to investigate whether gas leakage in pipelines sparked the fire and the subsequent blasts of ACs at the mosque.
The government has so far formed four committees to probe the deadly blast.
Some 40 people suffered burn injuries as all the air-conditioners of the mosque exploded during Esha prayers in Fatullah, Narayanganj on Friday night.
One of the injured died at night. Later, 23 other people succumbed to their injuries at Sheikh Hasina National Burn and Plastic Surgery Institute till Sunday afternoon.
Locals said the incident took place around 8:45 pm at Baitus Salam Mosque when the devotees had just finished their prayers.
An air-conditioner went off and sparked a fire inside the mosque. Later, the remaining six ACs exploded there, leaving the 40 devotees injured.
What fire service official says?
Deputy Assistant Director of Narayanganj Fire Service Abdullah Arefin said there was an underground gas line on the north side of the mosque.
Gas can accumulate inside the mosque due to gas leak from the line. Gas might have accumulated at the mosque for having ACs. An explosion can occur from a spark when someone turns the power switch on, he said.
Brigadier General Sajjad Hossain, director general of the fire service, said, “We’re sure there’s an underground gas line or there’s one very close to the mosque. We’re also investigating the issue of electrical short-circuit. We’ll also look into whether it is a sabotage. We’ll continue the investigation keeping all the issues open.”
Meanwhile, Dhaka Power Distribution Company (DPDC) disconnected the power supply to the area on Friday night following the incident.
A team from Titas Gas’ regional office visited the mosque on Saturday morning and disconnected the gas connection.
AC blasts or something else!
During a visit, the UNB correspondent found the six ACs installed on the wall burnt. The compressors of the ACs installed on the roof of the two-storey mosque were intact.
The electrical box for the AC line on the east-south corner wall of the mosque was also unharmed.
Shah Nizam, who came to offer prayers at the mosque, said had the ACs exploded, the walls would have collapsed but it did not happen so.“There might be another reason behind the fire,” he said.
A week ago, he said, gas was coming out from the gap between two tiles on the floor.Local people suspected that that gas was leaking from an underground gas line outside the north wall of the mosque.
State Minister’s visit
State Minister for Power, Energy and Mineral Resources Nasrul Hamid Bipu visited the spot on Saturday.He said the government has made all the arrangements for the treatment of those injured in the blasts.
Besides, Nasrul said, each of the families of the victims has been given Tk 20,000 for burial purposes.The cause behind the blast is being investigated separately by various government agencies, he added.
The government has formed four separate probe committees to investigate the incident.
A three-member investigation committee has been formed headed by the director of fire services (operations) while a five-member probe body has been constituted led by Titas Gas general manager (planning) Abdul Wahab Talukder. Another three-member investigation committee has been formed headed by Additional District Magistrate Khadija Taheri Baby. Yet, another committee has been formed, headed by Mojibur Rahman, chief engineer of DPDC to investigate the horrific incident.
