Greek authorities have arrested on the first woman suspect linked to the country's November 17 urban guerrilla group.
A police source said Mrs Angeliki Sotiropoulou, wife of the group's suspected top assassin, Mr Dimitris Koufodinas, was taken into custody after her fingerprints were found at one of the radical leftist group's Athens safehouses raided by police in July.
"They found her fingerprints on one of the apartment's walls which they consider enough evidence to call for her arrest," a source said.
Her husband turned himself in last week after three months on the run as Greece's most wanted man.
November 17, named after the date of a 1973 Athens student revolt against the then military junta, first gained notoriety with the murder of CIA station chief Richard Welch in 1975. Since then it has been blamed for killing 22 people including other foreign diplomats.
