There is suspicion among Central Bureau of Investigation (CBI) officials that former Unit Trust of India chairman P S Subramanyam and Renaissance Securities director Rakesh Mehta had been tipped off about Friday's CBI raids well in advance.
According to highly placed intelligence officials, on Thursday both Subramanyam and Mehta had engaged an international packing and moving agency to shift a lot of documents and personal effects from their respective residences to a safer hiding place.
