Artikel 13

1. Upon being satisfied, after an examination of information available to it, that the circumstances so warrant, any State Party in whose territory a person alleged to have committed a crime to which it applies this Convention in accordance with article 2 is present shall take the person into custody or take other legal measures to ensure the person's presence, in accordance with its domestic law. The custody and other legal measures may be continued only for such time as is necessary to enable any criminal, extradition or surrender proceedings to be instituted.
2. Such State Party shall immediately make a preliminary inquiry into the facts.
3. Any person in custody pursuant to paragraph 1 shall be assisted in communicating immediately with the nearest appropriate representative of the State of which the person is a national, or, if the person is stateless, with the representative of the State where the person habitually resides.
4. When a State Party, pursuant to the provisions of this article, has taken a person into custody, it shall immediately notify the States Parties referred to in article 8, paragraphs 1 and 2, of the fact that such a person is in custody and of the circumstances which warrant the person's detention. The State Party which makes the preliminary inquiry contemplated in paragraph 2 shall, as appropriate, promptly report its findings to said States Parties and shall indicate whether it intends to exercise jurisdiction.
