Police on Friday arrested an engineer for negligence in duty in connection with the worst building collapse in Bangladesh that left at least 509 people dead.
Abdur Razzak Khan worked as consultant when the owner of the eight-story Rana Plaza in suburban Savar illegally added three floors atop the ill-fated building, a police official told newsmen.
Sixty-three more bodies were on Friday retrieved from the debris 10th day into the collapse while the number of people rescued alive remained unchanged at 2,437.
The army-led salvage campaign would be carried out since the last of the body would be retrieved with the use of heavy equipment like hydraulic cranes and sophisticated electronic devices to remove the rubble and locate the bodies as part of the second phase of the rescue operations.
The four generators inside the garment factory building may have caused the disaster, a top investigator says.
