Greek authorities say police are seeking a convicted member of the deadly November 17 terrorist organization who broke the terms of a prison furlough.

Christodoulos Xiros, 55, had served 10 years of his six life terms for involvement in a string of assassinations by the far-left group. He failed to make an obligatory daily appearance Monday at a police station in northern Greece.

Public Administration Minister Kyriakos Mitsotakis voiced confidence Tuesday that Xiros would be recaptured, but said authorities should reconsider furloughs policy for those convicted of severe crimes.

Xiros had been granted a nine-day furlough, and was due to return to prison Thursday.

November 17, which mixed Marxist ideology with nationalism, killed 23 people between 1975 and 2000. It was broken after a string of arrests in 2002.
