UPPER DUBLIN, Pa.—Police in suburban Philadelphia are investigating a complaint from a parent who says innocent photos of several underage girls have been posted on a website that promotes pornography.

Upper Dublin police say the parent informed them that Facebook photos of eight to ten girls in the same circle of friends have appeared on a site next to links to pornographic material.

Police tell WPVI-TV ( http://bit.ly/Wymi7u) they don't know who swiped the photos and posted them on the smut site.
