Former NSE chief Ravi Narain to be produced before PMLA court today

iSec Services Pvt Ltd was hired for assessing cyber vulnerabilities, the CBI has said that the entity was used to snoop on employees, the reports said.

The contract was awarded to iSec for system audit of brokerages, including those accused of preferential access.

Narain's arrest comes a week after ED's Special Public Prosecutor NK Matta told a Delhi court that he, along with other accused, conspired to cheat NSE and its employees. They engaged with iSEC Services Pvt Ltd - the firm linked to Pandey - for illegal interception of phone calls of the exchange's employees in the guise of periodic study of cyber vulnerabilities of NSE, Matta was reported as saying before the bench by news agency PTI.

The ED action against Narain was preceded by the arrest of Ramakrishna, who was first held by the agency on March 6 in the co-location case, and was later arrested by the CBI on July 14 in the phone-tapping case.
