(CNN) A Pennsylvania man faces charges including sexual assault after police say they found him living with 12 girls, including an 18-year-old and two children he fathered with her.

Police in Bucks County, Pennsylvania, just north of Philadelphia, arrested Lee Kaplan, 51, on Thursday. Police said the girls living with Kaplan at his house ranged in age from 6 months to 18 years.

In a related case, authorities nearly 100 miles away in Lancaster County arrested the parents of the 18-year-old, with police saying the couple had "gifted" their daughter to Kaplan for helping them out of financial difficulties. She was 14 when her first child was conceived, the criminal complaint said.
