If during your stay in the Czech Republic, you´re unfortunate enough to feel the cold clamp of handcuffs around your wrists, know that (as a foreigner) you have the right to the presence of an interpreter during any interrogation. You also have the right to speak privately with a lawyer and to have him or her present during any questioning – be aware, however, that the lawyer cannot give you advice on how to answer a question that´s already been asked. Make sure that proper protocol is being followed by the police: they must note the time and place of your arrest, and if they do not have a court-issued warrant, they are obliged to release you after 48 hours. It would be wise to contact your embassy as soon as possible, since they will often have somebody on hand for dealing with just such an emergency.
