Athens -

Greek authorities on Tuesday launched a search for a suspected member of a far-left militant group after he failed to check in with police as required under the terms of his pre-trial release.

Costas Sakkas is awaiting trial on charges of belonging to extremist group Conspiracy of Fire Nuclei, whose members have been convicted of bombings.

He was released from a nearly three-year pre-trial detention in July 2013 after going on hunger strike for over a month, on condition that he report to his local police station in Athens every week.

He failed to check in with police on Monday and was declared a fugitive, a police source said.

A self-styled anarchist who denies involvement in the group, Sakkas was placed in pre-trial detention in December 2010 alongside several members of Conspiracy who were later convicted of bombings.

Sakkas was charged with alleged membership in the outfit after police said they had found his fingerprints on objects seized at an alleged Conspiracy hideout.

Conspiracy of Fire Nuclei, listed as a terrorist organisation by Washington, had sent parcel bombs to European leaders and embassies and carried out a wave of arson and bomb attacks.

Police in 2011 carried out several arrests and said they had dismantled the group.

However, there have since been sporadic arson hits against government targets in support of jailed Conspiracy members, many of them carried out in the name of an Italian-based outfit, the Informal Anarchist Federation. - Sapa-AFP
