A man pretending to be a wheelchair user who had taped 25kg of gold to his thighs has been arrested at Bangladesh's main airport.
Customs officials became suspicious when they saw that Jamil Akhter had travelled abroad 13 times this year.
The $1.5m haul is the largest this year as Bangladesh has emerged as a hub for smuggling gold into India.
Higher import duties on gold in India, the world's biggest gold consumer, have led to a surge in trafficking.
