Section 11 allows a District Court judge to permit the re-arrest and detention of a person in respect of an offence for which he or she was previously detained under section 30 of the Offences against the State Act but released without charge. This further period must not exceed 24 hours and can only be authorised in circumstances where the District Court judge is satisfied, on information supplied on oath by a member of the Garda Síochána, that further information has come to the knowledge of the Garda Síochána about that person's suspected participation in the offence and about which they wish to question the suspect. This section was utilised on two occasions.
