The move comes after authorities found either an airline crew or workers of ground handling companies allegedly involved in 80 cases of gold smuggling reported in past three years, official sources said.
All employees, including airlines crew, who have access to the incoming passengers need to be checked throughly every time they go out of the airport, they said.
The decision in this regard was taken at a recent meeting by the Directorate General of Revenue Intelligence (DGRI) with officials of airlines, immigration, Central Industrial Security Force (CISF), customs and Delhi International Airport Limited (DIAL), they said.
The airlines have been educated that they should report any suspicious passengers to the customs authority. Airlines, especially national carrier Air India and Jet Airways which have maximum number of flights from foreign destinations to India, have been told to identify such passengers pro-actively as they come to know in advance about the gold or other items being carried by them while screening and frisking their baggage, the sources said.
