Shirin Mansion, the three-storey building located in the city's Science Lab area which collapsed partially after an explosion on Sunday morning, has been declared ‘dangerous’ and 'abandoned' by Dhaka South City Corporation (DSCC). On Sunday afternoon, the DSCC authorities put up a banner declaring the building abandoned. Earlier, on Sunday morning, at least three people died and twelve were injured when the building partially collapsed due to an "explosion that triggered a fire" at Dhaka's Science Lab area. The deceased were Tushar, Shafikuzzaman, and Abdul Mannan.  

One woman in her 80s tripped over another resident who had fallen on the landing in a steep stairwell. Others got disoriented, even in their own apartments, and cried out for help.
