Dhaka, March 25 (IANS): Customs officials seized 105 kg of gold bars at Bangladesh's second largest airport in Chittagong Tuesday.

"We've seized 902 gold bars weighing about 105 kg wrapped in polythene bags and placed beneath passengers' seats shortly after a Biman Bangladesh Airlines flight landed here from Dubai at around 10 a.m.," an official of the Customs Intelligence Department said.

He said the seized gold was worth 450 million taka (about $5.77 million).

The official, who declined to be named, said 10 people, including some passengers of the flight, had been detained.

Seven of the detainees admitted their involvement in smuggling during primary interrogation, he said.

The official said this is the biggest haul so far at Chittagong airport.

In July 2013, customs officials in the country's premier Shahjalal International Airport in Dhaka seized 1,064 gold bars weighing around 124 kg from the luggage of a Biman Bangladesh flight.
