The teenager is currently being held in an Egyptian prison, on trial with around 420 others.
He was put on trial after a confrontation with security when Muslim Brotherhood president Mohamed Morsi was ousted from power.
He has been awaiting his trial for almost two years and his case was adjourned for the seventh time earlier this month.
In a letter to his family, the 19-year-old stated he feared he would be abused and tortured by the guards and told of how he had been put with forty others in a room designed for only ten.
Ibrahim told his family that he vowed to go on hunger strike until he is allowed home to Ireland.
According to the Department of Foreign Affairs and the Irish Embassy they have appealed for his release on bail, which would allow him to return to Ireland.
The next court date is set for August 2nd.
