The influential son of Bangladesh's former premier Khaleda Zia was freed from custody in the emergency-ruled country Wednesday, an official said. Tareque Rahman, once referred to as the most powerful man in Bangladesh during Zia's stint as premier between 2001 and 2006, has been granted bail although he still faces 13 charges of corruption. He is expected to leave Bangladesh for medical treatment as part of an effort by the army-backed government to ease tensions with mainstream political parties and restore democracy by the end of the year.
