BANGKOK, Feb. 8 (Xinhua) -- Thailand's Department of Special Investigation (DSI) on Friday asked prosecutors to formally charge wife of the ousted prime minister Thaksin Shinawatra and other two defendants for assets concealment involving the listed SC Asset Corp.

    Pornchai Assawawattanaporn, deputy director-general of DSI, in his capacity as chief investigator on the case submitted evidence to the prosecutors on Friday to charge the three defendants including Thaksin's wife Pojaman Shinawatra, and two female executives of SC Asset Corp. Both of the two are relatives to the former first lady and her husband, the state run Thai News Agency reported.

    Another defendant, deposed prime minister Thaksin Shinawatra is still living in self-imposed exile in overseas after his government was toppled in a military coup on Sept. 19, 2006. The court had earlier issued an arrest warrant for him.

    In January, the prosecutors allowed Pojaman to use her earlier bail amounting 2 million baht (about 60,600 U.S. dollars) in cash to give bail for herself.

    The DSI has charged the accused for concealing shares of SC Assets, a listed property developer, which violates the Securities and Exchange Act.
