Mohammad Refayet Ullah was arrested in Dhaka three months after the Rana Plaza building collapsed. Ullah, suspended after the tragedy, had been wanted for questioning over the nine-storey structure, housing garment factories, that flouted building codes. Police said his office allowed three extra floors in the building, which had permission for six and failed to take action when cracks appeared one day before the tragedy.
