You have the right to be treated fairly and with respect by the police.
You do not have to say anything to the police. BUT if you are later charged with a crime and you have not mentioned, when questioned, something that you later rely on in court, then this may be taken into account when deciding if you are guilty.
There may be good reasons why you do not wish to say anything to the police, and you should not be intimidated into answering questions. Get a solicitor down to see you in the police station as soon as possible.
There may be times when if you give an innocent explanation for what you have done, the police may leave you alone.
It is wise not to discuss the case with the police until you have consulted privately with a solicitor
If the police are about to arrest you or have already arrested you, there is no such thing as a friendly chat' to sort things out. Anything you say can later be used against you.
Think before you talk!
