The probe revealed that BoR's then promoters,led by Pravin Kumar Tayal,along with some companies that were connected to him and his relatives,by way of their continuous disclosure publicly announced that their stake had come down from 44.2 per cent as on quarter ending June 2007 to 28.6 per cent as on quarter ending December 2009.

In the same case,Sebi had slapped a total fine of Rs 5.75 lakh on two brokerage firms- RR Chokhani Stock Brokers and Angel Broking last month for allegedly carrying out trading for some clients who were related to the promoters of BoR and received payment for the trades from entities other than their clients.
