If you find yourself on the wrong side of the law and in
custody, the police are duty bound to explain what is happening to
you. If in doubt, ask them to explain what is going on and
why they have taken you into custody.
Your most important action is to get legal representation at the
soonest opportunity. Unless you know of a solicitor or
already have legal representation, it is your right to request to
see the Duty Solicitor.
You are also entitled to make a phone call so your best course
of action is to phone someone who is able to arrange for your legal
representation.
If you are charged, the charging officer will again explain what
this means and what will happen next.
