Now that South Korea's former leader Lee Myung-bak has been arrested, focus turns to the next stage of the investigation process. <br />It seems most likely that the prosecutors will visit the detention center to carry out their investigation. <br />Lee Jeong-yeon has the details. <br /> Prosecutors can now keep former President Lee Myung-bak detained for up to 20 days before he is formally charged.<br /> In principle, they are allowed to request his presence at the Seoul Central District Prosecutors' Office, but since the former leader refused to show up for his hearing, there's a high chance he could also refuse this request.<br /> So for now it seems most likely that the prosecutors will go to the Seoul Eastern Detention Center some time early next week.<br /> Lee will most likely be charged early April, so it doesn't overlap with major events such as the inter-Korean summit, the U.S.-North Korea summit, and the local elections,... all coming up in the next few months.<br /><br /> As for the actual sentencing, legal pundits are foreseeing a very long investigation process as there are more than 500 people to call as witnesses alone. Realistically it would be almost impossible to sentence him within 6 months.<br /><br /> His family members could also be the subject of investigation, including his wife Kim Yun-ok , his son Lee Si-hyung , his son-in-law Lee Sang-ju, as well as his brothers and nephews,... who are all linked with auto parts company DAS, the firm at the center of the case.<br /><br /> So possibly, for the first time ever, a former South Korean President may stand trial along with his family members as well as his close confidants.<br /><br />Lee Jeong-yeon, Arirang News<br />
