After Income Tax, it's now the turn of the Service Tax department to issue a notice of Rs 4.94 crore dues to Yoga guru Ramdev's trust for alleged duty evasion on its income raised through country-wide 'yog shivirs' (camps). The department's snoop and investigation wing, Directorate General of Central Excise Intelligence (DGCEI), has also launched a scrutiny of accounts of various activities conducted by the trusts run by Ramdev across the country post-2006.
