On Monday morning, 5 people were arrested in Dafni, for setting 2 surveillance video-cameras in fire. The police sent them to the public prosecutor suggesting 6 accusations, mainly criminal, aiming to the application of the anti-terrorist law (one of the accusations was the establishment of a terrorist group). Though, given the incapability to justify the accusations, the public prosecutor changed them. A lot of solidarity demostrators gathered immediately outside the court. The 5 arrestees, detained in the Athens Police Headquarters, sent a letter describing their arrest.
Update: On Thursday, at 9am, they were brought in front of the inquisitor and were set free. There was a solidarity rally outside the court.
