Recently, a warrant for Ko Young Wook's arrest was filed once again for the molestation of a middle school girl. This time, the court approved it. When he was asked if he will plead guilty to the charges made against him, he kept his words short and said “I’m sorry for causing problems. I will do the best to follow the court procedure.” Another arrest warrant had been filed earlier after he was charged with molestation of three minors last year which was dismissed by the court.
