The Central Bureau of Investigation (CBI), on Friday, questioned Chitra Ramkrishna, former chief executive officer and managing director of the National Stock Exchange (NSE), widening the ambit of its original probe in the case of preferential access to NSE algo-trading platform, an official of the agency said. The agency has also issued a look out circular against her."CBI is questioning Ramkrishna today in Mumbai and has issued look out circular against Ramkrishna, Anand Subramanian and Ravi Narain (former managing director of NSE). It is the expansion of the 2018 FIR in light of the recent facts that have emerged pursuant to the Sebi order," an officer with direct knowledge of the matter told Mint.
Chitra Ramkrishna is also facing allegations of irregularities over the appointment of Anand Subramanian as NSE's group operating officer and advisor to the managing director. Though the case dates back to the time when Chitra Ramkrishna was the managing director and the CEO of the National Stock Exchange, between 2013 and 2016, she has hit the headlines after Sebi issued an order recently saying Ramkrishna was "steered by a yogi" who stays in the Himalayas in the appointment of Subramanian.The CBI investigation, however, pertains to another scam that also took place during Ramkrishna's tenure. It was alleged that some traders got preferential access to NSE's co-location facilities like they used to log in early, got split-second access to the data feed in the exchange. It was also alleged that some traders had multiple IP addresses for accessing exchange data.
