Three suspected members of the Revolutionary Struggle urban guerrilla group were granted conditional release by a council of appeals court judges on Wednesday after almost exactly a year in custody.
Christoforos Kortesis, Evangelos Stathopoulos and Sarantos Nikitopoulos were allowed to leave jail after posting 3,000-euro bail payments and agreeing to report to their local police station twice a month.
Nikos Maziotis, a self-professed member of the group and its presumed leader, is to remain in custody along with his girlfriend Panayiota Roupa and the sixth suspect Costas Gournas.
The six suspects were arrested last April following police raids in Attica and other parts of Greece.
The group emerged in 2003 with the boming of an Athens court and subsequently claimed a string of hits on government and business targets. It is best known for firing a rocket-propelled grenade at the US Embassy in 2007.
