More than 500 bodies have been recovered from the Bangladesh building that collapsed last week, authorities said after an engineer was arrested over the disaster.
Abdur Razzak Khan had warned that the building was unsafe but is also accused of helping the owner add three illegal floors to the structure.
Mr Khan worked as the Rana Plaza owner’s consultant when the owner made the illegal addition to his five-storey garment factory building, police officials said.
Owner Mohammed Sohel Rana called Mr Khan to inspect the building after it developed cracks on April 23, local media reported.
That night Mr Khan appeared on television saying that after his inspection he told Mr Rana to evacuate the garment factory building because it was not safe. He has been arrested on a charge of negligence.
The elected mayor of Savar municipality, Mohammad Refatullah, has been suspended for alleged negligence in approving the design and layout of the doomed building, said Abu Alam, a top official of the local government ministry.
The confirmed death toll reached 501 as workers continued to pull bodies from the wreckage.
