The Drug Controller office, in a raid conducted over the last couple of days, has seized several lakhs of boxes of drugs with altered expiry dates.

“We got intelligence that such a racket was afoot in the city and based on this we conducted a massive raid in Chennai. Twelve teams raided 20–25 places, including pharmacies,” M. Baskaran, Director, Drug Control, said. Several blisters of drugs and bottles with date of expiry altered were found.

A retailer with wholesale licence was apprehended as was an unlicensed agent involved in distribution. The date on the blisters, whose expiry date was over, was removed using a solution and a new date printed on them.
