Why CTTC rules out terror attack

At least 19 persons were killed and over 100 injured after an explosion took place at a building in Gulistan's Siddikbazar area yesterday.

The Counter Terrorism and Transnational Crime Unit of Dhaka Metropolitan Police ruled out a terrorist attack or criminal incident, citing the following findings:

1. No traces of explosives or any sort of fragments or IED circuits.
2. No coloured or black smoke, indicating a "non-explosive" blast.
3. Bodies bearing no marks of shrapnel injuries.
4. Burn injuries above the waists of the injured, indicating gas existed at a height of around 3 to 5 feet, which is also a sign of methane gas blast.
