The seizure was made at the Karipur international airport last evening following a tip-off, Assistant Commissioner (Air Customs Intelligence) S P Shyam Sundar said today.
Based on information that one Hassinar of Thailangadi in Kasargod District was carrying huge quantity of gold, customs officials questioned him when he arrived here by an Oman Airlines flight.
Though he denied having brought any gold, customs officials following a search found a bill for seven kg of gold bought in Dubai in the flight's toilet dustbin, he said.
Both the passengers were arrested, Sundar added.
