WASHINGTON, June 19 (Xinhua) -- Police in the U.S. state of Pennsylvania have discovered 12 girls in residence of a man, who was later accused of sexually assaulting one teenager among the girls, according to local media.

Police searched the home of 51-year-old Lee Kaplan on Saturday after a neighbor called the authorities in growing concern about the weirdness of the house.

Kaplan was found living along with 12 girls from six months to 18 years. The 18-year-old told police that she and Kaplan had a 3-year-old and a six-month-old.

The teenager being sexually assaulted was given to Kaplan by her parents when she was 14 after the man helped solve a financial crisis of the family, said the police.

They said officials are working to verify where the other children were from.

Kaplan faces charges including sexual assault, unlawful contact with a minor, and aggravated indecent assault.
