The first trial of a prosecutor accused of assaulting and abusing a special public servant will begin on the 10th at the Osaka District Court for allegedly banging on the desk, telling the prosecutor, "Don't mess with the prosecution," and continuing to abuse him during an interrogation by the Osaka District Public Prosecutors Office's special investigation department. According to people involved, the prosecutor's office plans to maintain innocence, and the issue will likely be whether the prosecutor's words and actions amount to ``torture'' that causes mental and physical pain.
