Former chief secretary Jitendra Narain was grilled for the third day by Andaman and Nicobar Police and the Special Investigation Team (SIT) instituted to investigate the alleged gang rape of a 21-year-old woman in the union territory. After being questioned on two consecutive days, Friday and Saturday, the suspended 1990-batch IAS officer was grilled once again after a homestay in Port Blair was raided on Sunday in connection with the probe.
