After a Supreme Court-appointed committee indicted CSK principal Gurunath Meiyappan of betting during IPL-6, former IPL commissioner Lalit Modi Monday accused CSK skipper MS Dhoni of being involved in the cover-up of the incidents. Dhoni had earlier said Meiyappan had nothing to do with cricketing affairs of CSK. Moreover, Modi also asked for life ban on BCCI president N Srinvasan.
