On an application on oath made by a constable and supported by an information a magistrates’ court may extend a warrant of further detention issued under section 43 above if it is satisfied that there are reasonable grounds for believing that the further detention of the person to whom the application relates is justified.

Subject to subsection (3) below, the period for which a warrant of further detention may be extended shall be such period as the court thinks fit, having regard to the evidence before it.

Where a warrant of further detention has been extended under subsection (1) above, or further extended under this subsection, for a period ending before 96 hours after the relevant time, on an application such as is mentioned in that subsection a magistrates’ court may further extend the warrant if it is satisfied as there mentioned; and subsections (2) and (3) above apply to such further extensions as they apply to extensions under subsection (1) above.

A warrant of further detention shall, if extended or further extended under this section, be endorsed with a note of the period of the extension.

Subsections (2), (3) and (14) of section 43 above shall apply to an application made under this section as they apply to an application made under that section.

Where an application under this section is refused, the person to whom the application relates shall forthwith be charged or, subject to subsection (8) below, released, either on bail or without bail.

A person need not be released under subsection (7) above before the expiry of any period for which a warrant of further detention issued in relation to him has been extended or further extended on an earlier application made under this section.
