Officials of India’s Air Intelligence Unit (AIU) questioned the 48- year-old man after he arrived from Kuala Lumpur and recovered many bundles of diamonds from his luggage.
They acted on a tip-off that precious stones were likely to be smuggled from Malaysia, the AIU said in a statement.
Two white packets were found in his inner wear and eight inside a cooker in his checked-in luggage.
The 10 bundles contained 55 white mini ziplock pouches in which the diamonds were hidden.
Indian police are further investigating the matter, Malaysian’s Consul-Ggeneral in Chennai, Saravanan Karathihayan told Bernama on Sunday.
The passenger told the Indian customs authorities that he was supposed to deliver the diamonds to a person outside the airport.
However, no one turned up to collect the consignment when he was taken outside the airport and watched by police from a distance.
