Three Korean nationals were caught by customs officials at Siem Reap International Airport on Saturday bringing in 471 smartphones, according to a customs official.

Kong Sophallakun, chief of Siem Reap airport’s customs office, said the three Koreans – identified as Kang Donghwa, Kim Namgyu and Kong Sang Moon – brought the phones in on two separate flights from Seoul and Busan but had not paid the customs duty.

The first seized batch contained 265 phones and the second had 206 phones – mostly Apple, LG and Samsung products.

“Now all the phones are being kept at the customs office in the airport and we are waiting for the owners to get the approval from the custom department in Phnom Penh [to hand over the phones],” he said.

Sophallakun said that after the trio paid a fine and got an approval letter from the Phnom Penh customs office, the phones would be given back to the three Korean nationals. However, if they failed to pay the fine, he said further action could be taken.

He added that this was the first customs bust at the airport in 2016, with a few similar cases being registered last year.
