A German woman, 27, was arrested by the anti-terrorist squad on Friday, a development linked to the arrest for four local men on urban terrorism-related charges in two separate Athens locations a day earlier.
According to police, the woman is the daughter of a 55-year-old former "Red Army Faction" (RAF) operative, who herself was the subject of a 1993 international warrant by German authorities for participation in the ultra-leftist terror group.
Police said the woman had contacts with all four of the suspects.
The mother of the 27-year-old arrested in Athens had surrendered to Lebanese authorities in 1999.
