China has confirmed its detention of a South Korean footballer in relation to a bribery case.
Son Jun-ho, who plays in the Chinese Super League, is in police custody in the north-eastern Liaoning province, China's foreign ministry said.
The 31-year-old was detained at a Shanghai airport on Friday, according to South Korean media.
Reports of Mr Son's detention come amid a concerted crackdown on corruption and match-fixing in Chinese football.
Diplomats from South Korea will meet with Mr Son "to figure out exactly what kind of charges" he has been detained for, Yonhap News Agency reported, citing sources.
The country's foreign ministry said its mission in China was providing consular support to Mr Son, but declined to comment further.
China has arrested at least four football officials in the past three months for alleged wrongdoing.
Mr Son moved to China's Shandong province in 2021 where he played as a midfielder for Shandong Taishan.
The club won the Chinese Football League - the highest tier of professional football in China - that year. His current teammates include former Manchester United and Everton midfielder Marouane Fellaini.
He has also played 20 international matches for his home country, including in the Fifa World Cup last year.
A Korea Football Association official said it had sought an explanation from Shandong Taishan, but has not heard back from the club.
