In a sensational claim, D G Vanzara, a former IPS officer and an accused in the Ishrat Jahan alleged fake encounter case, said on Tuesday that Prime Minister Narendra Modi was secretly interrogated by the investigating officer. In his discharge application filed in the special CBI court, Vanzara said Modi, then the chief minister of Gujarat, was interrogated, but "such material was not placed on record of this case."
