(AP) — Police have charged a 20-year-old western Pennsylvania woman with sexually exploiting her sister — who is just 17 — by arranging for her to have sex with a man for money.

The Associated Press is not identifying the suspect to safeguard the identity of her sister.

But WPXI-TV (http://bit.ly/YS8cUu ) reports the woman is from Glassport and arranged the first tryst in December. In all, the woman is accused of arranging for her teen sister to have sex with the man twice before attempting to set up a third encounter with a different man.

Police say that final "deal" fell through when the alleged victim refused to provide nude photos of herself to the man.

The suspect faces a preliminary hearing April 23 on charges including promoting prostitution, sexual exploitation of children, and corruption of minors.
