A three-storey building that was built after filling up a pond has tipped over in the capital's Keraniniganj area Friday morning.
The incidence took place around 8:20pm when the building crashed down with some eight people trapped inside, reports UNB.
On information, Fire Service and Civil Defence members rushed to the spot and rescued them around 9:30 am, said Faruk Ahmed, in-charge of the local Fire Service office.
Five buildings next to the affected one have been deemed in danger and people have been evacuated from them.
"Taking risks, six families had been living in the building constructed without proper piling works," said Faruk.
Officer-in-Charge of Keraniganj Model Police Station Mainul Islam said residents from another five risky buildings adjacent to the collapsed one have been evacuated to avoid any risk.
Utility services, including gas and electricity, have been cut off from the buildings.
Fires and building collapses in Bangladesh
The incidents of building collapse and fire are occasionally reported in Bangladesh because of poor planning and the use of substandard materials.
On April 24, 2013, the collapse of the Rana Plaza building on the outskirts of Dhaka left at least 1,132 people dead and more than 2,500 injured.
Barely five months earlier, at least 112 workers had lost their lives in another tragic accident, trapped inside the burning Tazreen Fashions factory, also on the outskirts of Dhaka.
Seventy people died after a devastating fire raged through several apartment buildings used as chemical warehouses in capital Dhaka's old part, Chawkbazar, on February 21, 2019.
