Did MK Narayanan tamper with evidence of Rajiv's assassination?

West Bengal Governor and former Intelligence Bureau director MK Narayanan should be a worried man right now. Narayanan, whose stint as the governor of Bengal had his public persona cut out as that of a sociable, impeccably groomed diplomat, has been running into some rough weather of late.At first, he was criticised for being driven around in a brand new BMW en route to a Gandhi Jayanti function. Now, former chief investigator of the CBI, K Ragothaman has claimed in his book that Narayanan might have 'tampered with valuable evidence in the Rajiv Gandhi assassination case'.[caption id="attachment_507584" align="alignleft" width="380"] Rajiv Gandhi and MK Narayanan. Agencies[/caption]In a report published in today's DNA, Ragothaman talks about his new book Conspiracy to Kill Rajiv Gandhi: From the CBI Files and tells the reporter that while the CBI had started a preliminary inquiry in which Narayanan was named a suspect in hiding evidence, the case was buried by the then CBI chief.The video, which was reportedly shot just a few hours before Gandhi was killed at Sriperumbudur in 1991, was never shared by then IB chief Narayanan with the CBI to expedite the probe. Reportedly, Narayanan also wrote a 'secret letter' to then PM Chandrashekhar apprising him of the existence of the video.The book also points a finger at the possible role of MDMK leader Vaiko, then a DMK top gun. Ragothaman mentions how earlier in the day Gandhi was assassinated, several DMK meetings were 'abruptly cancelled' and DMK supporters, uncharacteristically, stayed away from all public meetings.Read the entire DNA story here.
