Market regulator Securities and Exchange Board of India – SEBI – will probe any lapses that might have occurred in the bribe-for-loan scam unearthed by CBI investigations two days ago. The investigation has led to the arrest of 8 financial services executives. Speaking to reporters on the sidelines of an ASSOCHAM conference in New Delhi on Friday, SEBI member Prashant Saran said the regulator will investigate any unusual activity and take steps to protect investor confidence. Finance Minister Pranab Mukherjee said there were no signs of insider trading taking place. CBI arrested at least eight persons including LIC Housing Finance executive Ramachandran Nair two days back involved in the scam. The agency also issued notices to 21 companies to provide all documents related to the case and explains any benefits received by them as also favours extended to the accused persons.
