Mumbai, Jul 4 (TOI): A 32-year-old from West Bengal, who ran two websites that were illegally procuring and selling live trading data of the National Stock Exchange (NSE), India's largest stock exchange, was arrested by the city cybercrime cell on Sunday.

Rajendrakumar Chell, a resident of Bardhaman district in WB, has been booked under the IPC section of cheating and under the Information Technology Act. The police are also looking for his associates, who helped him procure the confidential data from NSE. The complainant in the case is a manager with NSE who looked after business development for the exchange and was on deputation to DotEx, a fully-owned subsidiary of NSE.

DotEx has the rights to sell live trading data from NSE that include for trading in the capital market, futures & options, currency derivatives and wholesale debt market segments of the exchange. In October, DotEx learnt that live data for all these segments was openly available on a website (rtdsdata.com) for Rs 3,500 to Rs 5,000 per transaction. This was much less than the rate at which DotEX sold the data to its customers.

The complainant then called up the customer care number of the website and inquired whether NSE data was available. The customer care asked the complainant to deposit Rs 5,000 in a bank account of a firm named Orbtron International. "Immediately after the amount was transferred, the complainant was able to access the NSE data on two websites. This data is highly confidential and access to it is restricted only to authorized persons." said an officer.

The account was traced to Chell in West Bengal.
