Rescuers say they fear that hundreds more bodies are still inside the ruined structure in Savar.
Building owner accused
Blame for the disaster in the Bangladeshi news media is focusing on Sohel Rana, the owner of the building who was arrested at the weekend as he tried to flee the country.
Rana, a local leader of the ruling Awami League, is accused of telling the garment factory owners that it was safe for workers to reenter the building on April 24, the day it collapsed, even after cracks had appeared in the structure the day before.
He has denied pressuring the factory owners, according to the Bangladeshi news website bdnews24.com.
"It was them who forced me, saying they will face huge loss and shipments will be canceled if the factories were closed even for a day," the website cited him as saying Sunday.
At least six others, including three factory owners have also been arrested.
Also facing scrutiny are the Western clothing retailers who sourced their products from factories in the building, and Bangladeshi authorities accused by labor activists of allowing such disasters to happen through lax safety regulations.
In November, a fire at Tazreen Fashions Factory in another suburb of Dhaka killed at least 112 people.
The Bangladeshi government said Monday that it had decided to inspect the safety and security of all garment factories in the country.
