Athens, Oct 3 (IANS) The police in Greece have uncovered plans for imminent terrorist attacks against a series of business targets, Greek Public Order and Citizen Protection Minister Vassilis Kikilias said Thursday.

The announcement came after a booby trapped envelope at the Athens Stock Exchange was destroyed and hideouts were found in Athens and the northern city of Thessaloniki, Xinhua reported.

"At a difficult period for Greece terrorists were planning new attacks. The fight against terrorism is never ending," Kikilias told reporters, adding that notes found in an apartment at the central Athens district of Vironas Wednesday night indicated plans for an attack this weekend.

A 30-year-old man, who has been arrested, was not cooperating with police and his identity has still not been clarified, Greek Police Chief Dimitris Tsaknakis said.

However, police investigators link the detained person to the local urban guerrilla group "Revolutionary Struggle".

According to Tsaknakis police found fingerprints of Nikos Maziotis, the leader of Revolutionary Struggle, at the hideout. Maziotis was arrested after a failed robbery in central Athens in July.
