Refugee Action Coalition spokesman Ian Rintoul says 24 year old Hamid Kehazaei was evacuated from Manus after developing septicaemia from an infected foot.
Mr Rintoul says the asylum seeker had a heart attack following the infection and is now on life support in a Brisbane hospital.

Mr Rintoul told Sacha Payne says Mr Kehazai became rapidly unwell and his family been told he is brain dead.
