Police in Williamsport arrested 49-year-old Lawrence Newman on Tuesday and charged him with statutory sexual assault and related offenses.
A police affidavit says authorities received a letter about the relationship last month. Chief Lycoming County Detective William Weber says Newman and the girl initially claimed the child had been fathered by a teen from New Jersey, but later acknowledged having a sexual relationship.
According to court papers, Newman told police he tested positive for HIV several years ago.
Newman is being held on $20,000 bail. It was not immediately clear if he had an attorney.
Weber says the child is being cared for by family members.
