Article 6

Upon being satisfied that the circumstances so warrant, any State Party in the territory of which the offender or the alleged offender is present, shall take that person into custody or take other measures to ensure that person's presence. The custody and other measures shall be as provided in the law of that State but may only be continued for such time as is necessary to enable any criminal or extradition proceedings to be instituted.

Such State shall immediately make a preliminary enquire into the facts.

Any person in custody pursuant to paragraph 1 of this Article shall be assisted in communicating immediately with the nearest appropriate representative of the State of which he is a national.

When a State Party, pursuant to this Article, has taken a person into custody, it shall immediately notify the States Parties which have established jurisdiction under paragraph 1 of Article 4, and established jurisdiction and notified the Depositary under paragraph 2 of Article 4 and, if it considers it advisable, any other interested States of the fact that such person is in custody and of the circumstances which warrant that person's detention. The State Party which makes the preliminary enquiry contemplated in paragraph 2 of this Article shall promptly report its findings to the said States Parties and shall indicate whether it intends to exercise jurisdiction.
