According to reports in athens.indymedia.org, "Aggelioforos" newspaper received a phone call claiming responsibility for the arson against the offices late last night, in solidarity to the 17 persons that are prosecuted for the total destruction of their school during the time of its squatting against the intensification of the educational system. They also state that raids cant stop gas-canister attacks. It is also reported that they "sent e-mails to officials of the educational/juridicial system, (the president of the republic) Papoulias (former student of the same school that blamed the squatters in the media), the head-officer of the offices attacked and other persons. A hug for all vandalists".
