Marilyn Manson's former assistant sues him for sexual exploitation

Marilyn Manson's former assistant is suing the singer for sexual assault.

Ashley Walters has signed a lawsuit against the 52-year-old singer on Tuesday for sexual exploitation, manipulation, and psychological abuse while she was his assistant.

In her complaint, Walters claims that the singer offered her to sell drugs to his friends and showed her pictures of the underage girls he raped.

"He was looking to create an environment where Plaintiff was subjected to personal and professional sexual exploitation, manipulation and psychological abuse," the complaint, obtained by PEOPLE, alleged.

"It made me feel like I was his property. It just made me feel like a piece of meat," Walters, 37, told a media outlet. "You just put your head down and you're in survival mode. At the time I felt isolated like I couldn't go anywhere."
