If—
(a) a child or young person is serving a sentence of detention in a youth justice custodial centre; and
(b) the child or young person turns 24 years of age and 6 months—
before the child or young person turns 25 years of age, the Youth Parole Board must direct that the child or young person be transferred to a prison to serve the unexpired portion of the period of detention as imprisonment, unless the Board considers exceptional circumstances exist.
Note
This includes a child or young person who has been transferred to a youth justice custodial centre from a prison under section 674—see section 675.
