The daughter of former President Park Geun-hye's close friend was arrested on a plane to South Korea on Wednesday in connection with a massive corruption scandal.

Chung Yoo-ra, the 21-year-old daughter of Choi Soon-sil, was arrested by prosecutors on the flight from Amsterdam to Seoul after being extradited from Denmark a day earlier.

Chung had been held at a detention center in Aalborg, Denmark, since January. But South Korean prosecutors demanded she be extradited to face questioning on corruption allegations involving her mother and Park. The former president was removed from office in March.

South Korean prosecution officials took over the extradition process at a Copenhagen airport Tuesday.

Chung is scheduled to arrive at Seoul's Incheon International Airport in the afternoon.

Her extradition was accepted by a Danish court in April, after which she appealed the decision but then withdrew it last week.

Upon arrival, she is to be taken in for questioning on suspicions of receiving admission and grading favors at Ewha Womans University, as well as irregular funding for her equestrian training from Samsung Group. She is also expected to be questioned about her family's alleged overseas slush funds.

Prosecutors made the arrest with a pre-issued warrant. (Yonhap)
