Police believe that the discovery of what appears to be Revolutionary Struggle’s main hideout in Kypseli, near central Athens, earlier this week may also give authorities more information about another group, Sect of Revolutionaries, which claimed responsibility for the murder of a policeman last year. Sources said the date on which the fifth-floor apartment was rented could provide a link between the two groups. Revolutionary Struggle first appeared in 2003 and Sect of Revolutionaries carried out their first attack, on a police station in Korydallos, early in 2009. However, police believe the fact that the Kypseli property was rented in July 2008 may point to a falling out among members of Revolutionary Struggle with some splintering off to form Sect of Revolutionaries. Officers are basing this theory on the fact that Revolutionary Struggle’s arms and explosives were moved into the apartment more than a year after the group’s previous attack, at a time when there was no indication that authorities were close to finding the cache. «Fourteen months had passed since their last hit and they had no reason to transfer their weapons to a new hideout unless they wanted to keep some of their members from getting their hands on them,» an anti-terrorism squad officer who wished to remain anonymous told Kathimerini. This interpretation supports the theory that the Sect of Revolutionaries, which murdered a witness protection officer in Athens last summer, was formed by members of Revolutionary Struggle that wanted the group to be more active and more aggressive. Meanwhile, a 19-year-old woman, whose fingerprints were allegedly found at property where bombs were made by another group, the Conspiracy of the Cells of Fire, was arrested in central Athens yesterday, police said.
