Former president Chen Shui-bian (陳水扁) was yesterday returned to Taipei Prison after receiving medical treatment at a hospital in Taoyuan County.

Chen, who is serving a 17-and-a-half-year sentence for corruption, was granted a temporary release from Taipei Prison on March 6 for a medical checkup at Taoyuan General Hospital. Chen was found to be suffering from acute coronary syndrome and underwent a cardiac catheterization on Thursday.
