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.

　　On Thursday, the nation's textile industry reopened, a week after a work shutdown prompted by the building collapse near Dhaka.

　　The mayor of Savar, the site of the collapse, was suspended from office Thursday as garment workers returned to their jobs.  Local officials say charges will be brought against Mohammad Refat Ullah in connection with the country's largest industrial disaster.

　　Meanwhile, rescue workers are continuing to use heavy equipment to clear the site. Officials expect the number of victims to rise as 150 people remain unaccounted for.  More than 3,000 people were in the building when it collapsed.
