NEW DELHI, Aug 26 (INP): An Indian Navy officer, who recently left service after proving that a Vice-Admiral manipulated the system to promote his son-in-law and in the process almost wiped out all Russian-trained nuclear submarine operators, has now written to the Prime Minister naming at least three serving officers who actively assisted in the subversion. Lieutenant-Commander S.S. Luthra has called upon the Prime Minister to deal with the conspiracy as nuclear treason, the Indian media reported. In his case before the Armed Forces Tribunal, Lt. Commander Luthra established that Vice-Admiral P.K. Chatterjee’s efforts to promote his son-in-law resulted in the wiping out of an almost entire generation of Russian-trained nuclear submarine operators of India out of service.   INP/AH
