Ibrahim Halawa has asked Enda Kenny to intervene in his detention and free him from his prison in Cairo.
21-yr-old Halawa was detained during Muslim Brotherhood protests in Cairo in 2013.
He was one of 400 people who were accused of conpiracy for murder.
According to RTE, Halawa said:
“I am currently writing this with the most pain in my life but a worst pain has just attacked me, a mental pain… How much I feel abandoned,” he wrote.
“Tell me without hiding behind your finger, how do I feel towards my own government? The one I have hanged the flag of above me in my cell over my 35cm sleeping space.
“I hanged it even though they have left me to die in one of the worst prisons in Egypt without trying to move me. They have left me as a kid beaten and tortured to sit and watch all the other nationalities leave to their home.”
