CBI arrests another key accused Sanjay Gupta in the NSE co-location case

The Central Bureau of Investigation (CBI) on Wednesday arrested Delhi-based stock broker and Managing Director of OPG Securities Sanjay Gupta in the NSE scam, four years after the agency registered an FIR against him for preferential access to the market through multiple IDs and secondary servers called co-location facility. The CBI charged that Gupta along with some people attempted to destroy some evidence and also tried to influence SEBI officials which were probing the NSE co-location scam case.

National Stock Exchange’s (NSE) former chief Chitra Ramkrishna and chief operating officer Anand Subramanian are already in prison since March after the Court dismissed their bail petitions.[1]

CBI had summoned Sanjay Gupta to its headquarters where he was questioned about these issues, said CBI officials. During the questioning, Gupta was “evasive” and tried to “mislead the investigation” resulting in his arrest on Tuesday night, officials said. They said Gupta had allegedly approached members of a syndicate to bribe SEBI officials on his behalf and influence the investigation, they said. The CBI is probing whether the bribes paid to the syndicate members reached SEBI officials or not, they said.

The agency swung into action after a damning SEBI report in February this year in which strictures were passed against the then NSE CEO and Managing Director Chitra Ramkrishna and Group Operating Officer Anand Subramanian. It is alleged that OPG Securities consistently logged in first on selected Tick-by-Tick servers of the NSE for four years on most of the trading days between 2010 and 2014 and also had access to servers that had better hardware.

A tick is a minimum change in the price of the security. It is alleged that the Tick-by-Tick architecture used by the NSE was manipulated by brokers to remain ahead of peers during trading hours. Deloitte Touche Tohmatsu, which did a forensic review of the NSE’s Co-location facility, found that OPG Securities was the first in most cases during trading sessions.

The special court had repeatedly questioned the CBI about the action it has taken against other accused — Gupta and OPG Securities–named in the FIR. The CBI has alleged that Gupta was one of the main beneficiaries of the co-location facility started by the NSE which helped him get favorable access to the market over other brokers through multiple logins and access to secondary servers giving him a crucial time advantage and resulting in a multi-fold increase in profits of his company in just two years.

In the NSE, co-location scam-selected players had market price information before others as the stock market was using Tick-by-Tick technology in algorithm-based trading and co-location services of which Gupta was a beneficiary. The facility allowed the users to get access to the prices ahead of others, they said. The probe has so far established that during the period 2010-15 when Ramkrishna was managing the affairs of NSE, OPG Securities, one of the accused in the FIR, had connected to the secondary POP server on 670 trading days in the Futures and Options segment, said the CBI.

CBI officials said the investigation is going on in the role of the then senior NSE officials who were looking into the co-location which is understood to have given “unfair advantage and wrongful gain” to certain stock brokers including OPG Securities at the cost of others.

  1. Such moves by BJP are illegal, anti-national & is heading towards death of democracy. It is nothing but vendetta politics. BJP broke all protocols i.e. should have corrupted parties to keep the money instead of putting cases & attaching such money. BJP has many other avenues to earn money, maintain status protocol, you loot & we also loot by turns !! but no legal enquiry on each other.
