A member of the all-male pop group Tokio has been referred to prosecutors on suspicion of engaging in an indecent act with a high school-aged girl, investigative sources said Wednesday.

Tatsuya Yamaguchi, 46, allegedly kissed the girl against her will at his home in Tokyo's Minato Ward in February, the sources said, adding the police referred the case to the prosecutors last week.

Johnny & Associates, the talent agency managing Tokio, acknowledged the incident and released a statement from Yamaguchi saying he feels "deeply sorry for kissing the victim without considering her feelings after drinking alcohol."
