Mumbai, March 3 :    Mumbai, March 3:  The Securities and Exchange Board of India and the two premier bourses of the country-Bombay Stock Exchange and National Stock Exchange-have decided to turn the heat on the bear cartel which is suspected to have manipulated the crash in stock prices yesterday. The three have formed a fact finding committee which will visit offices of the member brokers alleged to be part of the cartel. The committee will start inspecting the records of those brokers who are suspected to have caused the crash in the stock markets. 'I would' not call it a probe or an investigation,' Anand Rathi, president of the Bombay Stock exchange (BSE), told The Telegraph, confirming that his exchange was contacted by Sebi, perturbed by the dramatic fall in the markets. It is a fact finding mission to inspect the records of certain market players, he added. The team headed by a Sebi member will have representatives from the market regulator's office and the two exchanges-BSE and NSE. The team will head for the offices of members of stock exchanges to ascertain for themselves whether a bear cartel is functioning which led to the dramatic decline in the stock markets yesterday, a Sebi official said. The finance ministry is also said to be worried over yesterday's bear hammering. Sources at Sebi say the scrutiny is the first of its kind in the history of Indian stock markets. Officials of the capital market regulator today confirmed that an investigation has begun with the help of the stock exchanges but declined to give further details. 'The unusual movements of the sensex and whether certain entities are trying to take advantage are being analysed,' Sebi sources said adding that 'activities of certain foreign institutional investors and broking firms,' are being looked into.
