The law enforcers arrested Shahadat Hossain, who had been running the illegal business, during the seven-hour raid ending at 7:00pm. The raid was conducted following a tip-off, Lt Commander Arif of Rab-1, who led the operation, told The Daily Star.

Mixing several types of powdered chemicals with distilled water, the unscrupulous businessman used to bottle the substances first. Then he pasted labels of reputed pharmaceuticals, like GalxoSmithKline, and marketed those, the Rab commander said.

The several thousand bottles of fake medicines included Eveux-B, Veril Rix, Hiberix, with price ranging from Tk 350 to Tk 1,350 per bottle, he added.

Besides, syringes, packaging materials and some other items were also seized from the spot.

Shahadat confessed that he sold those fake medicines in Mitford wholesale market.

On Thursday, members of Rab-10 seized 2,160 bottles of spurious medicines of Pustiplus brand, 1,000 empty bottles and 2,000 corks from Mitford medicine market.

None could be arrested during the drive.
