The Halawa family is pleading with the Tánaiste and Minister for Foreign Affairs to intervene and ask for the Egyptian authorities to release their son from prison immediately.
18 year old Ibrahim Halawa from Dublin has been locked up in a jail near Cairo for the past nine months.
He was detained last August along with his three older sisters in Cairo, following a day of protest against the ousting of former President Mohammed Morsi.
One of his sister's Somaia says the family's terrified he may be executed - following the mass sentencing to death of hundreds of inmates in Egypt's prisons.
