New Delhi, Oct. 14 -- The Enforcement Directorate (ED) on Monday carried out raids in Chennai as part of a money laundering probe into the manufacturing and supply of Coldrif cough syrup, linked to the deaths of 22 children in Madhya Pradesh, with officials alleging that profits derived by the company - Sresan Pharma - are "proceeds of crime". The federal financial crimes probe agency's multiple teams targeted seven locations in Chennai during the raids, including the residence of Sresan Pharma owner - G Ranganathan, key officers of drug control department of Tamil Nadu, manufacturing unit of the company and other places. Ranganathan was arrested by Madhya Pradesh and Tamil Nadu police on October 9 while two state drug inspectors were suspended by the Tamil Nadu government for failing to inspect Sresan's plant in the last two years as required under the law. ED officials said their probe under the prevention of money laundering act (or PMLA stems from two cases - a first information report (FIR) filed by the Madhya Pradesh police against Sresan Pharma alleging that syrup manufactured by them was adulterated and "was a direct cause for death of 21 children"; and a separate case in which the director (in-charge) - P U Karthikeyan - of Tamil Nadu Drug Control department was arrested red handed by the state Directorate of Vigilance and Anti-Corruption (DVAC) in July. "The profits derived by sale of adulterated cough syrup, which resulted in the death of 21 children, are proceeds of crime. The drug officers who did not do regular inspections and allowed production of adulterated cough syrup failed in discharge of public duties," said an ED officer. A second officer said ED will look at a larger corruption in the matter. Officials added that Ranganathan will be questioned after taking his custody from the Madhya Pradesh police....
