Two men and a woman who are being held in connection with Friday's €7.6m Bank of Ireland robbery are due before the High Court this afternoon challenging the lawfulness of their detention. They will claim the warrants issued by the District Court last night to extend their detention are invalid. Seven people, six men and a woman are being held in connection with the robbery early Friday morning during which a bank official was forced to withdraw €7.6m from the Bank of Ireland on College Green in Dublin while his family were held hostage in Kildare. Their periods of detention were due to expire at 9.55pm last night and the district court granted extensions of 24 hours in all 7 cases. At least three of those being questioned are due before the High Court shortly claiming their detention had expired last night before the judge issued warrants extending it. Lawyers for one of the men has already said the hearing of an application for an extension in his case only started at 10.45pm, that is 50 minutes after the previous period expired. All three will claim they are being unlawfully detained.
