Police in Nikaia, near Piraeus, yesterday were questioning two men, aged 41 and 32, believed to be members of a ring behind a series of nightclub bombings. Officers arrested the two suspects on Monday night after finding a homemade explosive device in the car of the 41-year-old. According to police, the device – a bucket containing 2 kilograms of gelatin dynamite, a high-impact explosive, and two detonators – was virtually identical to bombs used in two other blasts: one at the Polis nightclub on Petrou Ralli Street in Aegaleo, western Athens, on October 30 and the other at the Thea venue on coastal Poseidonos Avenue, southern Athens, on December 2. Police arrested a 25-year-old Albanian in connection with the Thea blast. He and the two suspects arrested on Monday are believed to have been taking orders from an unidentified convict thought to be running an extortion ring from jail.
