Police on Thursday turned over to prosecutors their case against popular television celebrity Shinsuke Shimada, 48, who allegedly struck and injured a female employee of his agency, Yoshimoto Kogyo Co.

Shimada, whose real name is Kimihiko Hasegawa, has admitted hitting the 40-year-old woman, investigators said.

Shimada got into an argument with the woman at a television broadcasting station in Osaka's Kita Ward on the afternoon of Oct. 25, dragged her into a dressing room, grabbed her hair and slapped her head, police said.

The woman suffered a mild neck sprain as a result of the assault, they added.

Shimada was quoted as telling police he felt the woman "had a bad attitude" and wanted to "teach her to behave as a person belonging to the same agency." The woman has said she was struck several times; Shimada told police he only hit her once.

Shimada held a news conference to say he was "100 percent" to blame for the incident. He said that although the woman talked to others in a rude way that needed to be "corrected," his actions could not be condoned.
