What you say in a record of interview can significantly impact the course of your case. Therefore, before answering questions, you should always contact a criminal lawyer for advice, regardless of whether you are innocent or guilty. Depending on the circumstances, a lawyer may advise you to answer questions from the police, provide a written statement or answer 'no comment'.
You will always be given the opportunity by the police to call a lawyer before an interview commences. We highly recommend doing so.
