The Hungarian was arrested in Gwangju on Sunday (July 28) after an incident in a nightclub, before being released and told he could not leave the country for 10 days.

Twenty-two-year-old Kenderesi has admitted touching an 18-year-old woman but denies sexual harassment. 

Police have now requested that he be indicted, according to South Korean news agency Yonhap.

Kenderesi, who won Olympic bronze in the men's 200 metres butterfly at Rio 2016, has reportedly asked to return to Hungary after paying a court a sum equivalent to the estimated fine.

"I'm sure everyone has a lot of questions about my Korean police case," the 2014 Youth Olympic gold medallist said in a post on Facebook.

"To avoid confusion, I would like to share what really happened. 

"On Saturday night, in a nightclub on the way back from the restroom to the dance floor, I touched the buttocks of a Korean dancer standing at the counter. 

"I did not even stop behind her, perhaps making a single reckless move that made the girl concerned very angry and make a complaint against me. 

"For the sake of clarity, I would like to say that I did not grope or grab the 18-year-old girl in the crowd. 

"Realising the seriousness of the situation, I have shown full cooperation throughout.

"The police were told they had security camera footage of the case, though this had not been shown to me. 

"Based on this, I sincerely trust that my words will prove that I have not committed any serious offence. 

"But what I really have to understand is that, without any willful intent, I have violated certain moral norms that underlie the local value system. 

"I am sorry for what happened, I would like to apologise to the Korean girl if I really hurt her. 

"However, I completely reject the accusation of sexual harassment."

Kenderesi finished last in the men's 200m butterfly final at the Gwangju World Championships on Wednesday (July 24).

The alleged nightclub incident took place about 24 hours after a loft at a nightclub in the city collapsed, killing two and injuring 16. 

Eight foreign athletes competing at the World Championships were among those hurt.
