"The company is taken aback by the discovery of cash at one of its offices by the investigating agency. It has taken a very serious view of the matter and has instituted an internal team of senior managers to make a thorough investigation and report its findings at the earliest.
Meanwhile, CBI today claimed to have made a fresh recovery from the group which included retail invoice of gold coins totalling to Rs 94 lakh, investments in various schemes to the tune of Rs 17 lakh besides Rs 24 lakh 'petty cash'.
