What is Arguido?

Legal Definition
Arguido (male, Portuguese pronunciation[ɐɾˈɡwidu]) or arguida (female, [ɐɾˈɡwidɐ]), normally translated "named suspect" or "formal suspect", is a status in Portuguese type legal systems, including those of Portugal, Angola and Mozambique. It is given to a person whom the authorities suspect may have committed an offence. This designation does not exist in certain other jurisdictions. In a criminal investigation a person has to be declared an arguido prior to being arrested. Portuguese law makes a distinction between arguido and suspect.
