A direction shall, if it has not previously ceased to have effect, cease to have effect at the expiration of such period as may be specified in the direction (being a period not exceeding two months beginning with the date of the direction), unless continued in force by a further direction.

Where, by virtue of a direction, a young person is held in custody in a prison or other place and the direction ceases to have effect (whether or not by reason of the expiry or cesser of section 4 above) it shall be lawful for him to continue to be held in custody in that prison or place until arrangements can be made for him to be held in custody in accordance with the law then applicable to his case.

Nothing in subsection (2) above shall be taken to make lawful the holding in custody of any person who would, disregarding that subsection, be entitled to be released from custody.
