SEBI steps up surveillance system

 Sebi had recently levelled insider trading charges against high profile fund manager Samir Arora while taking investment decisions for Alliance Capital Mutual Fund (ACMF).

 According to sources, Sebi chairman G N Bajpai has taken a keen interest in this initiative. Bajpai was not available for comment.

 The regulator is keeping a tab on investment bankers and mutual funds, which are generally privy to price sensitive information.
