Principal Commissioner of Customs C Rajendiran told reporters that in 2013-14 gold seized at the Vizag Airport was 6.67 kg, valued at Rs 2.01 crore, while in 2014-15, gold seizure was 7.62 kg, valued at Rs 2.04 crore, he said.
In 2015 so far, gold seized is 11.06 kg, valued at Rs 3.06 crore, he said.

Smugglers bring gold from Dubai and give it mid-air to domestic passengers travelling between Hyderabad and Visakhapatnam, since domestic passengers can escape from the terminal with nominal scanning, he said.
Though Visakhapatnam Airport has been operating three international flights namely Dubai-Vizag, Singapore-Vizag and Kuala Lumpur-Vizag, most gold smugglers refer to take Dubai-Vizag flights.
Airport customs sleuths have arrested 17 people in connection with gold smuggling since 2013 and Rs 3.75 crore of customs duty has been collected, he said.
