GREEK anti-terrorist police arrested three people today in connection with a series of firebomb attacks against conservative party politicians that left one person dead and injured another four, authorities said.

The predawn bombings in the northern city of Thessaloniki on July 1 targeted the homes of members of Greece’s governing conservative New Democracy party.

The 72-year-old mother of parliamentary candidate Afroditi Nestora was killed after a crude bomb made with camping gas canisters exploded under Ms Nestora’s car, which was parked at the entrance of her apartment building.

Ms Nestora herself suffered burns and remains in hospital.

Police said today that they arrested a 29-year-old man in the northern city of Thessaloniki and a 26-year-old woman on the southern island of Crete on suspicion of involvement in the bombing at Ms Nestora’s home, as well as one other man suspected of hiding the two in his flat before and after the attack.

Police said the search for others potentially involved in the series of attacks continued.
