Iako niko nije preuzeo odgovornost za bombaški napad na zgradu suda, mnogi su ga odmah povezali s krajnjim ljevičarskim ekstremističkim grupama, čiji se broj nasilnih napada na zgrade vlade, policijske stanice i banke povećao od decembra 2008, kad je policija u Atini ubila jednog tinejdžera.
While no one has claimed responsibility for the courthouse bombing, many linked it immediately to far-left extremist groups, whose violent attacks against government buildings, police stations and banks have increased since December 2008, when police killed a teenage boy in Athens.
