Chen Shui-bian, former President of the Republic of China, stepped down on May 20, 2008, the same day that Ma Ying-jeou took office as the new President of the Republic of China. About an hour after he left the Presidential Office Building, as a former President of the Republic of China and no longer enjoying presidential immunity, he was arrested and restricted from leaving the nation by Taiwanese prosecutors due to allegations of corruption and abuse of authority. Chen was accused of fraud in a case involving the handling of a special presidential fund used to pursue Taiwan's foreign diplomacy. However, the Special Investigation Division dropped money-laundering charges because of a lack of evidence.
