13-3888. Method of arrest by officer without
warrant


When making an arrest without a warrant, the officer shall inform the person to be
arrested of his authority and the cause of the arrest, unless the person to be arrested
is then engaged in the commission of an offense, or is pursued immediately after its
commission or after an escape, or flees or forcibly resists before the officer has
opportunity so to inform him, or when the giving of such information will imperil the
arrest.
