Section 6: Arrest, custody, etc., of offenders against Nigerian law

(1) Nothing in section 4 or 5 of this Act shall affect-
(a) any powers of arrest, search, entry, seizure or custody exercisable under Nigerian law with respect to offences committed or believed to have been committed against that law; or
(b) any obligation on any person in respect of a recognisance or bail bond entered into in consequence of his arrest, or the arrest of any other person, for such an offence; or
(c) any power of any court to remand (whether on bail or in custody) a person brought before the court in connection with such an offence.
(2) Where a person has been taken into custody without a warrant for such an offence as aforesaid committed or believed to have been committed against Nigerian law, and there is reasonable ground for believing that in accordance with section 2 of this Act he is subject to the jurisdiction of the service courts of a country to which this section applies, then, with a view to its being determined whether he is to be dealt with for that offence under Nigerian law or dealt with by the service courts of that country for an offence under the law of that country, he may, notwithstanding anything in any law relating to criminal procedure, be detained in custody for a period not exceeding three days without being brought before a court, magistrate or justice of the peace; but if within that period he is not delivered into the custody of a service authority of that country, he shall as soon as practicable after the expiration of that period be released on bail or brought before a court, magistrate or justice of the peace having jurisdiction to deal with the case.
