New Delhi, Mar 29: The National Investigation Agency has nabbed a Trinamool Congress, state secretary Chhatradhar Mahato for allegedly bringing armed tribals to hold a trainload of the Rajdhani Express passengers and crew hostage in West Bengal.
His arrest comes days after the Calcutta High Court had exempted from custodial interrogation by the NIA in another case registered in 2009 relating to the murder of a CPM activist in Lalgarh.
