More than 70 South Koreans accused of aiding scams were extradited from Cambodia on Friday morning aboard a chartered flight.

The Korean Air flight from Phnom Penh, carrying 73 suspects, landed at Incheon International Airport at 9:41 a.m.

This marks the fourth case in which a group of South Korean criminals has been extradited on a chartered aircraft, and the largest such operation ever conducted involving a single country.

All of the suspects were taken into police custody immediately after boarding the aircraft, as arrest warrants had already been issued.

Upon arrival, the suspects were transferred directly to police facilities across the country for questioning.

Police suspect the individuals defrauded 869 South Koreans of approximately 48-point-six billion won, or around 33 million U.S. dollars.
