It is a well-known procedure in criminal law that in arresting an accused or when “inviting” a person by the police authorities for some questioning on some acts or omissions contrary to law allegedly made by them, a warrant of arrest or a search warrant issued by judges shall be presented and read to the accused, this being in accordance with the Constitution[i] and the Revised Rules of Criminal Procedure[ii].in recognition to due process accorded to an accused. No person can be detained or taken by authorities unless a warrant of arrest has been presented by them, lest any evidence taken throughout the search or arrest is inadmissible in court, being the fruit of the poisonous tree. However, a warrantless arrest is likewise permissible in certain situations and any evidence taken therefrom is admissible, such being a product of a search incidental to the valid warrantless arrest.
