A former leftist terrorist suspected of involvement in the 1977 slaying of then West German federal prosecutor Siegfried Buback was arrested on Thursday, German authorities announced Friday afternoon.
Federal prosecutors said that 57-year-old Verena Becker was detained at her Berlin home.
Prosecutors launched a new investigation into Buback's assassination this year based in part on the analysis of new DNA samples. They believe Becker played a key role in the planning and carrying out of the April 7, 1977, attack that left Buback and two others dead.
Becker was a member of the Red Army Faction leftist terrorist group at the time.
