If police are investigating an indictable offence (e.g., theft, robbery, trafficking, fraud or assault charges), they will ask you to participate in a Record of Interview.
The Record of Interview: Allegations and questioning of suspects
Police ask many people to attend a police station for an interview about criminal allegations. Generally this is not arrest but a “taking into custody”. Under the Crimes Act (Vic), police must read you your rights and, if necessary, explain them before they can question you.
When an interview is over, the interviewing official, generally a police officer, may release you without charge. This can be pending a summons, or bail to attend a court hearing. Sometimes your answer is sufficient and the result will be no charges.
