Prosecutors said Wednesday they have indicted the former chief of the country's top steelmaker POSCO over alleged bribery and breach of trust which cost the company more than a hundred billion won in losses. Chung Joon-yang is suspected of providing kickbacks to Lee Sang-deuk, the elder brother of former President Lee Myung-bak, to solve one of the company's key problems - a height limitation on its factory buildings, the Seoul Central District Prosecutors' Office said in a press briefing.
