Customs Intelligence officials recovered 48 abandoned gold bars, weighing over 15 kilogrammes, at Hazrat Shahjalal International Airport in Dhaka in the early hours of yesterday.
The bars, wrapped in sticky tape in nine packets, were left in a trash bin at a washroom in boarding bridge area, said Shahidul Islam, director general of Customs Intelligence and Investigation Department (CIID).
However, no one was arrested in this connection, he added.
CIID officials said smugglers sometimes left gold in this manner to avoid arrest. Many with security passes work as their agents and take the gold out of the airport.
The director general of CIID said they are investigating yesterday's incident.
