A voluntary police interview is an official police interview that is subject to the same legal procedures as one conducted following an arrest. Anything you say or choose not to say can still be used as evidence in court if you are later charged, making it just as significant as an interview conducted following arrest. The key difference is that, during a voluntary interview, you are not under arrest, will not be searched, and are not detained. You are free to leave at any time; however, if you attempt to leave before the interview has concluded, the police may decide to arrest you to ensure the interview continues.
