Sinha also found fault with business development team for introducing buyers with bad credentials into the NSEL system.
He blamed the warehousing team for not having adequate control of physical stock and making "false stock statement".
An FIR was registered in the case on September 30 by the EOW against Jignesh Shah, chairman and managing director of Financial Technologies which promoted the crippled exchange, Joseph Massey, MD of MCX-SX, the stock exchange promoted by the FT Group, and other promoters, directors and defaulters.
All of them have been charged with cheating, forgery, breach of trust and criminal conspiracy, among other offences, in connection with the payment crisis at the NSEL.
On October 1, the Central Bureau of Investigation too registered a preliminary inquiry in the case.
NSEL has been facing problems in settling Rs 5,600 crore dues of 148 members/brokers, representing 13,000 investor-clients, after it suspended trade on July 31 on government's direction.
