Greek police arrested three people, including two foreign nationals, following a police raid in the Zografou university campus in Athens on Saturday morning.
The three individuals - a Greek man, an Argentinian man and a Swedish woman - have been charged with breach of the peace. They will be led before an Athens public prosecutor, while the police are continuing a preliminary investigation.
The police raid targeted student halls of residence in the campus and was carried out after a series of torchings of parked vehicles in the area surrounding the campus.
After an extensive search of the rooms, police found a number of incriminating objects, including flash-bang grenades, tear gas grenades, helmets, clubs, 27 empty beer bottles, masks and full-face hoods, a burnt Greek flag, banners, as well as handwritten and printed material containing anarchic content. They also confiscated a laptop, micro-camera and a pair of gloves.
