New Delhi (Agencies): The Anil Ambani group on Friday said it has identified the stockbrokers spreading malicious rumours and "baseless sensational charges" against it and sought immediate action by SEBI against the perpetrators.

ADAG said these brokers were sending out mass emails and SMSs and were also making large-scale voice calls with baseless and sensational charges against its firms.

Stocks of various companies belonging to the Reliance Anil Dhirubhai Ambani Group have fallen sharply in the past few weeks and the group has blamed corporate rivals, a cartel of stock market manipulators and 'rumour mongering' for this heavy sell-off.

However, the group has already sought an investigation by SEBI, the stock exchanges and investigation agencies into the matter, it said in a fresh statement on Friday that it has "identified stockbrokers sending mass e-mails/SMS/voice calls with baseless sensational charges against ADA Group."

"These brokers (are) guilty of blatant violation of SEBI (FUTP) Regulations," the group said. These regulations relate to Fraudulent and Unfair Trade Practices (FUTP) relating to the securities market.

It also sought a "full-fledged SEBI investigation and punitive interim orders against guilty brokers".
