Convicted terrorist Dimitris Koufodinas, currently serving 16 life sentences for his role as the notorious hitman of the terror group November 17, was on Friday transferred to the "open" agricultural prison in Volos from the high-security prison in Korydallos.
The order for the transfer was given by the Central Committee for Transfers overseen by the justice ministry.
Under the law, the transfer of a prisoner to an agricultural prison (which is defined as an open prison by law) must be preceded by an application from the prisoner in question.
Koufodinas, a leading member of the now disbanded November 17 terrorist organisation that was also known as "Poisonhand" has been convicted of committing a series of murders carried out by the group.
Washington and Ankara have both openly slammed the decision by Greek authorities to move Koufodinas from high-security Korydallos Prison in Athens to the agricultural jail in the town of Volos, central Greece.
