India is the largest importer of gold after China.
An alert has been issued by the Directorate of Revenue Intelligence, lead agency to check smuggling and customs duty evasion, to all international transit points across the country, official sources said.
The World Gold Council, which represents the mining industry, puts India's demand between 850 and 950 tonnes in 2014.
Despite the recent imposition of import rule and high duties, the yellow metal continues to attract buyers.
In the past two years, investors in gold have lost money.
The council is looking at the youth as a segment in the global market and has started the LoveGold on the social media (Facebook and Twitter).
Be a disciplined investor for attractive returns, says fund managers.
