Bangladesh Factories Death Toll Passes 500

Workers and army personnel toil in the collapsed garment factory building in search for bodies, 

May 2, 2013 in Savar, near Dhaka, Bangladesh.

Police in Bangladesh have arrested the engineer who warned of cracks in an eight-story factory complex that collapsed last week, killing more than 500 people.

Abdur Razzak Khan last week warned of cracks in the building a day before it collapsed. Police say they arrested him because of his role in the original construction of the building. This brings to nine the number of people arrested since the factory collapsed April 24.

Among the detainees were the owner of the building, the owners of several factories housed inside, and engineers responsible for its construction.

Police said Friday the death toll has risen to 501, as new bodies were discovered in the ruins overnight.
