Nalco Chairman and managing director A K Srivastava and three others arrested yesterday by CBI will be produced in a Delhi court later today. The investigation agency arrested Srivastava after his wife had accepted 3 kg of 24 carat gold from the wife of a middleman who was brokering a deal between the CMD and a Madhya Pradesh-based private group of companies. Later, a search of Mr Srivastava's wife's locker resulted in the seizure of seven more gold bricks of 1 kg each. Ten kg of gold and 30 lakh rupees in cash have been seized from the lockers. The overall value of the gold, at current prices, comes to approximately over 2 crore rupees . All the four accused, Srivastava, his wife, the middleman and his wife will be produced in the court.
