The Congress in Goa on Tuesday questioned Chief Minister Manohar Parrikar's silence on the issue of probing a factory, whose owner allegedly has BJP links and which was busted for illegally manufacturing date-rape drug ketamine by the DRI.

"Parrikar should stop being silent over the seizure of ketamine, known as a date-rape drug, from the factory owned by his party office bearer. I dare the Chief Minister to come on record to declare that BJP office bearers are not in drug trade in Goa," state Congress president Girish Chodankar said in a press statement issued on Tuesday.
