Ibrahim Halawa's mum has been summoned to the Egyptian jail where the Firhouse teen's being kept, over his deteriorating health.
It's understood he has chest pains that are getting worse and his family fear he's inherited his dad's heart condition.
The 19 year old has been locked up after being arrested during protests in Cairo in 2013.
Ibrahim's mum received word from the wife of a doctor who is jailed alongside him.
