The AIU officials said that they received a tip off from the Narcotics Control Bureau (NCB) based on which they intercepted the woman identified as Vanessa De Kock who was holding a South African passport.
"Examination of her baggage resulted in recovery of 4.9 kg of Methaqualone stuffed inside 10 envelopes of cardboard and was wrapped inside salwar suit fabric kept inside checked baggage," an AIU official said.
