Senior IAS officer S.M. Raju is among 16 persons accused by Bihar's vigilance bureau of committing financial irregularities to the tune of Rs 9.75 crore in a scheme meant for granting scholarships to students from the scheduled castes and tribes. The vigilance investigation bureau lodged the complaint against Raju and 15 other public servants and middlemen at the vigilance police station in Patna on Thursday. Raju, a 1991 batch IAS officer who is also known as an inventor of Ayurvedic medicines, is at present posted as additional member in the board of revenue. This is the second time that Raju has been booked on a corruption charge. In 2003, he was arrested in Karnataka on the directive of the southern state's Lokayukta for allegedly accepting Rs 21 lakh as bribe from the principal of a college to help students clear the entrance test for the Industrial Training Institute (ITI).
