BARCELONA (AFP) – Spanish police said yesterday they had arrested six members of what they described as an anarchist cell suspected of a parcel bomb attack on the Greek Consulate in Madrid earlier this month. One of the suspects – five men and a woman, all Spanish nationals – had been arrested by Greek police in Thessaloniki during anti-globalization riots on June 21 at the Halkidiki European Union summit. The six were arrested late on Monday on suspicion of involvement in «acts of urban terrorism» in the Barcelona region and of posting a booby-trapped book to the Greek Consulate on September 8, an Interior Ministry statement said. The bomb was defused by Spanish explosives experts. Handguns, a sawn-off shotgun, chemicals, fuses and two manuals on explosives were found during police searches of the homes of the six people. Soon after the attack on the embassy, police in Athens let it be known they thought the attempt might be linked to the arrest of two Spanish demonstrators in Thessaloniki.
