An Athens court on Wednesday acquitted anarchist Costas Sakkas, 30, over charges of violating his restricted-residence order. Sakkas, who is accused of being a member of the Conspiracy of the Cells of Fire urban guerilla group, was arrested on Tuesday.

Police said that Sakkas had spent the night at a house in Neo Psychico, northern Athens, where he was arrested, effectively violating an order that restricted him to spending the night at his family's residence in Piraeus.

Sakkas had been arrested on December 4, 2010, outside an apartment in Nea Smyrni, southern Athens, where arms were being hidden.

He was granted conditional release in July after going on hunger strike to protest the fact that he was being held in detention for two-and-a-half years, when the maximum period for pretrial custody was 18 months.

He denies being a member of Conspiracy of the Cells of Fire.
