IBERVILLE PARISH- Authorities have arrested a man accused of sneaking into a family's home, raping a 6-year-old girl and threatening one of her relatives.

According to the Iberville Parish Sheriff's Office, 52-year-old Patrick Callegan of White Castle was questioned after he allegedly raped the girl Sunday morning. Callegan reportedly entered the home without permission and sexually assaulted the child.
