Another convicted member of the November 17 terrorist group was regularly granted furlough, including to attend IT classes in Athens, Kathimerini has learned.
Iraklis Kostaris was given normal furlough and study leave to attend lessons at a technical college, it emerged.
He was also part of a team of 50 inmates responsible for making and delivering bread to hospitals and prisons around the country.
Since the disappearance of fellow N17 member Christodoulos Xeros, Kostaris has been moved back to Korydallos Prison and his furlough canceled.
Xeros, who is serving six consecutive life sentences plus an additional 25 years in prison for his role in six assassinations as well as other terrorist activities, has been on the run since January 17.
Kostaris is serving a life sentence for his role in the terrorist organization.
