Bhubaneswar: Sleuths of the Directorate of Revenue Intelligence (DRI) on Tuesday seized 8.5 kg of marijuana worth Rs 3 crore and detained three passengers who arrived from Bangkok at Biju Patnaik International Airport (BPIA) here.DRI officers said this is the second time a marijuana consignment has been seized at the airport this month. Three days ago, 5.291 kg of marijuana had been seized. This was the 14th time DRI had seized the contraband since Jan 2025, DRI officials said.The three passengers, who were in possession of multiple packets of marijuana packed as food items, were the carriers. Their identities have not been disclosed. All three are from Kolkata, a DRI officer said.“A big suitcase was used to pack the marijuana. The bottom of the trolleys looked as if there was no layer down. But on scrutiny, we found a chamber where the packets had been hidden. The marijuana was packed like chocolates,” said a DRI officer. The consignment was meant to be taken to Kolkata by road, interrogation of detained passengers revealed, the officer added.DRI officers said the high-quality marijuana was grown using the hydroponic method. DRI and customs officers are interrogating the passengers, who, before boarding the flight in Bangkok, managed to escape mechanical scanners and security personnel.DRI officers said moments after the flight took off from Bangkok, they received a tip that the huge marijuana consignment was coming to BPIA. “We positioned our staff and took the help of customs officials too. The scanners provided hazy images, but physical checks revealed the contraband. Each packet was unwrapped and weighed,” the officer added.
