The first group of South Korea's Olympic delegation has returned to Seoul.

The 139-member delegation, comprising athletes and coaches in 15 sporting events, including judo and table tennis, arrived at Incheon International Airport Thursday morning via a chartered flight from Athens.

Athletes who arrived in Seoul Thursday included Olympic table tennis gold medalist Yoo Seung-min, wrestling gold medalist Lee Won-hee and badminton gold medalists Kim Dong-moon and Ha Tae-kwon.

Gymnast Yang Tae-young, who was apparently robbed off a gold medal due to a scoring error last week, remains in Athens to keep a close watch on developments in the ongoing controversy.
