Artikel 10

1. Where, as a result of action taken under Article 9, the intervening State has evidence that a relevant offence has been committed which would be sufficient under its laws to justify its either arresting the persons concerned or detaining the vessel, or both, it may so proceed.
2. The intervening State shall, without delay, notify the flag State of steps taken under paragraph 1 above.
3. The vessel shall not be detained for a period longer than that which is strictly necessary to complete the investigations into relevant offences. Where there are reasonable grounds to suspect that the owners of the vessel are directly involved in a relevant offence, the vessel and its cargo may be further detained on completion of the investigation. Persons not suspected of any relevant offence and objects not required as evidence shall be released.
4. Notwithstanding the provisions of the preceding paragraph, the intervening State and the flag State may agree with a third State, Party to this Agreement, that the vessel may be taken to the territory of that third State and, once the vessel is in that territory, the third State shall be treated for the purposes of this Agreement as an intervening State.
