Section 27

Where an immigration officer is in doubt as to the right of any person to enter Singapore, it is lawful for that officer to direct the person to an immigration depot and, in that case, that person must proceed immediately to that depot and must remain there until permitted to leave by that officer.

No person shall, except on the written order of the Minister, be so detained for any period exceeding 7 days except that the Controller may, in his or her discretion, and pending the completion of inquiries regarding that person, release that person from the immigration depot on such terms and conditions as the Controller may think fit, and for that purpose the Controller may issue to that person a pass in the prescribed form.

Any person who refuses or neglects to comply with any directions given by an immigration officer under subsection (1), or who leaves an immigration depot in contravention of that subsection, shall be guilty of an offence.
