A Vietnamese who broke through Incheon International Airport has been arrested after five days in hideout.
Yonhap News said police in South Korea and its Justice Ministry officials are questioning the 25-year-old on how he came to smuggle himself into the country and whether he received help.
Police arrested the man Daegu, 237 km south of Seoul, which is near an area of a large Vietnamese community.
A source from Vietnam embassy in South Korea said the man wanted to find a job there.
He flew from Hanoi to Seoul on Friday morning and was supposed to transit to Japan according to his ticket, the report said.
But he forced open an automated immigration gate at Incheon airport and escaped in two minutes.
An alarm at the checkpoint went off but the official in charge of the post was not there. The airport was only aware of his sneaking nearly three hours later as he did not show up for the flight to Japan.
Korea Immigration Service under the Justice Ministry plans to seek charge of violating the nation’s immigration control law against him, the report said.
According to Yonhap, the Board of Audit and Inspection, South Korea's state audit agency, plans a "massive inspection" of Incheon airport after a recent series of security breaches.
