After you are informed by the police that they are investigating you for committing an offense, you may be asked to come to the station to conduct an electronic interview. You may or may not be under arrest at this time.
Usually, you are not under arrest, which you will be informed that you do not have to participate in the interview if you do not want to. A solicitor would advise that the decision to participate in the interview varies with the circumstances.
Sometimes it is beneficial to participate in the interview with a lawyer present and sometimes you should not participate at all. The decision depends on the nature of the offense. The normal process would involve the police showing up to your residence, where you would voluntarily go to the police station.
The police are obliged to give you your rights and allow you to call a friend, relative or lawyer of choice. The police must give a reasonable time for your person of choice to reach the station. You cannot be disadvantaged in the interview, otherwise, the interview is deemed to be not sufficiently complied with the legislation.
The basis of an electronic record of interview involves you providing your story to the police so they can get the bigger picture and reach a conclusion on the events that transpired.
