Chennai Customs officials seized 4,639 grams of hydroponic ganja from a passenger arriving from Kuala Lumpur and arrested him on Sunday.
The passenger was intercepted based on profiling during screening of his check-in baggage. Officials found 49 packets containing a greenish lumpy substance that tested positive for ganja using a narcotic drug detection kit.
The seizure was made under Section 43(a) of the Narcotic Drugs and Psychotropic Substances Act 1985. The passenger has been remanded to judicial custody.
Further investigation continues into the case.
