The anti-narcotics agency also said that it was unable to trace the importer of the illicit drugs while no clearing agent showed up to clear the drugs, which was imported into the country in two batches from Indian.
The seized consignments were imported into the country through the United Arab Emirates (UAE) airline, Etihad Cargo.

He declared that the approved milligrams for Tramador by the Federal Government was 50m and 100m, but decried that the seized consignment was 250m, which indicated that the importer internationally imported the high milligrams for wrong purpose.

He said: “We collected the consignments from the Skyway Aviation Handling Limited (SAHCOL) shed today (Thursday) and we got to know of the consignment even before it arrived the country through our foreign intelligence. Since then, we have been monitoring it and waited for either the importer or any clearing agent to come forward for clearance, but no one came.
‘The approved dosage for Tramador is between 50m and 100m, but what the importer brought into the country was 250m, which is above the approved milligrams by the government. The total waybills were five.
