DHAKA, Bangladesh (AP) - Bangladeshi police have arrested the engineer who warned that a building housing garment factories was unsafe a day before it collapsed.
Police official Ohiduzzaman said Abdur Razzak Khan worked as the Rana Plaza owner's consultant when the owner illegally added three floors atop his five-story building.
Khan was arrested Thursday on a charge of negligence.
He appeared on television after inspecting the building April 23 and said it was unsafe. Police ordered it evacuated, but the order was ignored and it collapsed the next day.
Authorities also Friday raised the confirmed death toll to 487. It's the deadliest disaster to Bangladesh's $20 billion-a-year garment industry that supplies global retailers.
