(2)An order for the detention of an offender under this section may be made for the following term, that is to say—

(b)in any other case, a term of three months.
(3)An order under this section shall not be made in respect of any person unless the court has been notified by the Secretary of State that a detention centre is available for the reception from that court of persons of his class or description, or an Order in Council under subsection (5) of section three of this Act is in force in respect of persons of his age and sex.
(4)An order under this section shall not be made in respect of a person who is serving or has served a sentence of imprisonment for a term of not less than six months or a sentence of borstal training unless it appears to the court that there are special circumstances (whether relating to the offence or to the offender) which warrant the making of such an order in his case; and before making such an order in respect of such an offender the court shall—
(a)in any case, consider any report made in respect of him by or on behalf of the Prison Commissioners,
(b)if the court is a magistrates' court and has not received any such report, adjourn the hearing under subsection (3) of section fourteen of the Magistrates' Courts Act, 1952, and remand the offender in custody to enable such a report to be made ;
