REHABILITATION CENTRES REGULATION - SECT 21

Offenders may be kept apart pending adjudication of disciplinary offence

When an offender has been reported for a disciplinary offence, the
Officer-in-charge may order him to be kept apart from other offenders, pending
adjudication if and only if he is satisfied-

   (a)  that such order is necessary to prevent collusion between the 
        offender concerned and other offenders in respect of the disciplinary 
        offence in the interest of the administration of justice; or

   (b)  that such order is necessary to protect the offender concerned from
        potential harm from other offenders, or vice versa.
