Section 411: Offences commited in foreign ports or on the high seas by officers and seamen of Nigerian ships

(1)
Whenever a complaint is made to an appropriate officer in a foreign country that-
(a)
person who is, or has within three months previously been, employed as a master, seaman or cadet on any Nigerian ship, or on any unregistered ship which is required to be registered in Nigeria, has committed an offence against property or persons at any place outside Nigeria, whether on shore or afloat; or
(b)
that any master, seaman or cadet belonging to any ship referred to in subsection (1) of this section has committed an offence on the high seas, the appropriate officer may inquire into the case upon oath or affirmation, and may, if the case so requires, take any steps in his power to place the person alleged to have committed the offence under the necessary restraint and send the person as soon as practicable in safe custody to Nigeria.
(2)
The appropriate officer may order the master of any Nigerian ship, which is not a ship of the Nigerian Navy or its Reserve bound to Nigeria to receive on board and afford a passage and subsistence during the voyage to a person alleged to have committed the offence under subsection (1) of this section, and to any witness.
(3)
Where an appropriate officer requires the master of a ship to receive an alleged offender or any witness as provided in subsection (2) of this section, the appropriate officer shall endorse upon the agreement of that ship such particulars, with respect to every person so received on the ship, as the minister may require.
(4)
Any master of a ship to whose charge any person alleged to have committed an offence is committed shall, on the ship's arrival at a port in Nigeria to which the ship is bound, give the alleged offender into the custody of a police officer or constable.
(5)
A master of a Nigerian ship, who when required by an appropriate officer to receive and afford a passage and subsistence to any alleged offender or to any witness, refuses to do so or does not deliver any alleged offender committed into his charge into the custody of a police officer or constable as provided in subsection (4) of this section, commits an offence and on conviction is liable to a fine not less than one hundred thousand Naira.
(6)
The expense of placing any person referred to in subsection (1) of this section under restraint, and of conveying him and any witnesses to Nigeria in any manner other than onboard the ships to which they respectively belong, shall, where not paid as part of the costs of the prosecution, be paid by the Minister.
