The CBI on Saturday conducted searches against brokers at more than 10 locations in different parts of the country in connection with the alleged National Stock Exchange (NSE) co-location scam.
The searches were carried out in Delhi, Mumbai, Kolkata, Gandhinagar, Noida and Gurugram.
Last month, the agency had filed a chargesheet against the former NSE managing director, Chitra Ramkrishna, and its former group operating officer Anand Subramanian.
