A 33-year-old woman faced arraignment Sunday on charges alleging she offered to let an undercover investigator take pornographic photos of her 7-year-old daughter and have sex with the girl, authorities said.

The woman was arrested Friday after meeting with the investigator, the Wayne County sheriff's department said in a statement Sunday.

Authorities said the woman offered to let the investigator take the photos and, when she met with him, discussed being paid in exchange for sex with the child, the Detroit Free Press reported.

The name of the woman, who lives in this Detroit suburb, wasn't being released to avoid identifying the child, the sheriff's department said.

She faced five charges, including child sexually abusive behavior, illegal use of the Internet for child sexually abusive actions or materials and distribution of child sexually abusive material, said department spokesman John Roach.

If convicted, she could get up 20 years in prison.
