Fire kills last Bangladesh survivor A blaze broke out in the wreckage of a Bangladesh factory block, killing a woman whose 110-hour battle for survival touched the nation following its worst industrial disaster. Earlier, the owner of the complex, property tycoon Sohel Rana, was detained as he attempted to cross into India and was flown back to Dhaka where he will face charges over the building's collapse, which has so far claimed 381 lives. Firefighters were seen weeping live on television after failing to save the female garment worker, a widowed mother-of-one identified as Shahnaz, whose courageous struggle became a symbol of hope in the wake of the catastrophe. The fire broke out as we were cutting a beam to bring out what we believe was the last remaining survivor from the collapsed building. We managed to douse it, but as we came back we saw her dead," Ahmed Ali told AFP. She was a brave lady and fought until the end. We worked for 10-11 hours today just to try to bring her out alive. We took the challenge but we lost. Three rescuers were also injured in the blaze which was put out in a matter of minutes, fire service director Zihadul Islam said. More bodies are expected to be found as workers, who had been digging manually to avoid harming survivors, switched to using earth-moving equipment to lift slabs and reinforced concrete to clean-up debris. Firefighter Abul Khayer, who spoke to Shahnaz throughout the rescue attempt, said she had an 18-month-old son. She clung on for the boy ... She told me you're my brother, please don't leave me alone. The eight-storey Rana Plaza, which collapsed on Wednesday morning, violated building regulations like many structures around the capital Dhaka. A police spokesman said they had also arrested Anisur Rahman, owner of Ether Tex garment factory. He is the fourth garment factory owner held by authorities. By Sunday evening, the confirmed death toll had reached 381, according to police officer Liakot Hossain. About 2,500 people have been rescued from the scene of the disaster, some only after undergoing amputations to free them from the pancaked slabs of reinforced concrete.
