Customs officials said that Suresh Kumar Nagarajan, a Chennai resident, was about to fly to Kuala Lumpur when he was intercepted.
Screening of his check-in baggage showed some suspicious substance inside, while a sniffer dog too indicated that something was wrong.
On opening his suitcase, officials found that he had hidden 2,002 grams of Methaquolone (also called Mandrax), a banned recreational drug worth Rs 2 crore in illicit international markets, in a specially-made cavity.
