The Seoul Central District Prosecutors' Office will begin interrogating Choi Pyeong-seok, a senior executive at Samsung Electronics Service, at 10 a.m., the office said.
Prosecutors are expected to probe him over his suspected influential role in sabotaging the establishment of the labor union under the company's so-called master plan to block any moves toward the forming of a labor union and to prevent its activities.
Prosecutors have been questioning company officials to find out if the alleged sabotage by the Samsung affiliate were handled by those in higher positions in the tech giant, possibly including Samsung Electronics' leadership or Samsung Group's now-disbanded control tower. (Yonhap)
