Article 198

①A public prosecutor, public prosecutor's assistant officer or judicial police official may ask any suspect to appear in their offices and interrogate said person when it is necessary for the investigation of a crime; provided however, that the suspect may, except in cases where said person is under arrest or under detention, refuse to appear or after said person has appeared, may withdraw at any time.

②In the case of the interrogation set forth in the preceding paragraph, the suspect must be notified in advance that said person is not required to make a statement against said person's will.

③The statement of the suspect may be recorded as a written statement.

④The written statement set forth in the preceding paragraph must be inspected by the suspect or read to said person for verification, and if said person makes a motion for any addition, removal or alteration, said person's remarks must be entered in the written statement.

⑤If the suspect affirms that the contents of the written statement are correct, said suspect may be asked to attach a signature and seal to it; provided however, that this does not apply when the suspect refuses to do so.
