Ten of the women who have come forward have given their names. Five spoke on the condition that they not be named, saying they feared repercussions.

The woman who said Schwarzenegger spanked her in 2000 at the post-production studio said Saturday that she had decided to tell her story when the candidate seemed to dismiss the accounts of women who said he had groped them. Had he not run for governor, she said, she would never have come forward.

The woman said she wished to remain anonymous because she works in the entertainment industry.

In the summer of 2000, she was working part time at a West Los Angeles sound studio, where Schwarzenegger was doing post-production work on the film "The Sixth Day," she said.

The woman said she had introduced herself to the actor in the recording studio and told him to let her know if he needed any coffee, juice or snacks. Shortly after she left the room, the woman said, Schwarzenegger and another man came out. The man said Schwarzenegger wanted his raisin bagel toasted, the woman said.

She said Schwarzenegger followed her to the kitchen, spun her around, pinned her to his chest and swatted her buttocks five or six times. Then, she said, he whispered in her ear: "This is what should happen at your house every morning."

"I was so frightened and angry at the same time," the woman said. "There was a certain sense of powerlessness.... I never commented [to him]. The level of embarrassment was pretty severe."

When Schwarzenegger loosened his grip, the woman said, she ran out. But Schwarzenegger followed, grabbing her hands and commenting on her lack of a wedding ring, she said. As she started walking back to the recording studio, she said, Schwarzenegger told her: "By the way, I love it that you're not wearing underwear." The woman said that she retorted: "I am wearing underwear, you idiot."

"It was playful for him," she said. "It was not at all playful for me."

The woman said she told the facility's coordinator, Jeff Schwartz, about the incident but declined his offer to pursue the matter with his bosses. "I told him: I was a grown-up and I can handle it, but if anything like this happens again I'm going to take action."

Schwartz, interviewed Saturday, said he remembered her complaint.

"She definitely was taken aback and shocked," Schwartz said. "The big thing was that he actually smacked her on the butt. I definitely felt it was inappropriate."
