Former Irish Defence Forces soldier Lisa Smith, who is to be tried on a charge of membership of terrorist organisation ISIS, is due to spend the weekend in Limerick Prison.
This is despite being granted bail on Thursday.
The Louth mother and former Air Corps member was expected to be released from the jail on Friday, where she is being held on remand.
However her bail was not taken up.
As part of her bail terms, Ms Smith must lodge €500 and an independent surer must lodge €1,000 with the courts.
Ms Smith has been remanded to appear before Dublin District Court on January 8th.
