New Delhi, March 6 : The Central Bureau of Investigation (CBI) on Sunday arrested Chitra Ramakrishna, former CEO of National Stock Exchange (NSE), in an alleged Co-location case. Sources said that Ramakrishna’s anticipatory bail application in the Co-location case was dismissed by the Trial Court on Saturday. The alleged NSE Co-location scam took place between 2010 and 2014, in which certain brokers had allegedly gained unfair access to the Co-location facility of NSE, enabling them to access the data feed of NSE a split-second faster than others. A split-second faster access is considered to result in huge gains for any stock trader. CBI registered a case regarding this on May 28, 2018, and was currently investigating the matter. CM RJ
