One of the owners of the building that collapsed in Bangladesh Wednesday—killing more than 300—is being held by authorities. Officials say Mohammed Sohel Rana had been in hiding since the incident occurred, until he was captured by the Rapid Action Batallion while attempting to cross the Indian border. At the site of the building collapse, rescuers are continuing to pull survivors from the wreckage four days later. A group of nine victims, all of whom are alive, are allegedly stuck under rubble too massive for humans to lift. Heavy machinery is likely to arrive today in hopes of facilitating the rescue.
