The mass trial of Ibrahim Halawa has been postponed until next Saturday.
It's reported the trial was put back to the 19th of December because one of 492 defendants wasn't in court today.
The 20 year old from Firhouse spent his third birthday in jail on Sunday, where he's been locked up awaiting trial for more than two years.
He's been behind bars since he was arrested in Cairo for protesting in August 2013.
So far, Ibrahim has not been formally served with any charges, so it's not known what it is he is facing.
In a statement from the Department of Foreign Affairs it says, “Ireland’s Ambassador to Egypt, Damien Cole, represented the Irish Government at today’s hearing in Cairo and spoke directly both with Ibrahim’s family and with his Egyptian lawyer.
It went on to say "Officials from the Embassy have attended all hearings to date and this Irish citizen and his family have been the recipients of comprehensive consular assistance from the Department.
Embassy officials have paid 48 consular visits to Mr Halawa, most recently on 23rd of November.
This level of attendance and consular visitation underlines the importance the Government attaches to the case."
Ibrahim's sister, Somaia, told 98fm news that they're disappointed about the postponement.
She says while it's good that Taoiseach Enda Kenny has been speaking to Egyptian President Abdel Fattah el-Sisi, she feels not enough pressure is being put on authorities to secure her brothers release:
"This can't continue to happen to Ibrahim and there has to be an end to that. So it's a good step, but I think we need to follow it and pressure it more and more".
She added that the next trial date on Saturday is unusual for Ibrahim's case:
"It's different, I hope it's positive. I don't know why, this time it's really different, it's not even a week".
Ibrahim's barrister Katie O'Byrne from London firm Doughty Street Chambers, has been speaking exclusively to 98FM News about the 20-year-old's case.
"Obviously we all know how very important those years are, between 17 and 20 and what Ibrahim is actually missing out on in terms of his own life, and being able to live the life of an ordinary teenager and ordinary young person".
Human rights groups and others say that keeping Ibrahim in prison for so long without facing a court goes against all international principles of justice and humanity and are constantly calling for his immediate release.
Somaia and her family are travelling to Strasbourg where a European Parliament debate, backed by all Irish MEP's, will take place on Thursday.
