The bars, each weighing one kg, were seized from the two buses for the Spicejet flight which arrived here from Dubai, Air Intelligence Unit (AIU) officials said.
AIU acted on intelligence received and passenger profiling, and intercepted a passenger from Moovattupuzha at the exit gate after he had completed his immigration check and collected his baggage, they said.
On being questioned, he admitted that he had concealed eight gold bars beneath the last row seat in the bus. It was searched and the gold recovered, they said.
