If an immigration control officer finds that there are reasonable grounds to believe that a person clearly falling under any of the items of Article 24 is likely to flee before the issuance of a written detention order, the officer may detain the person without a written detention order.
If detention has been carried out as set forth in the preceding paragraph, the immigration control officer must promptly notify a supervising immigration officer of the grounds for the detention and request the issuance of a written detention order.
In the case referred to in the preceding paragraph, if the supervising immigration inspector does not approve the detention set forth in paragraph (1) (limited to cases in which the inspector finds that the person does not fall under any of the items of Article 24), the immigration control officer must immediately release the person detained.
