A Northampton County man is facing charges after police say he had unlawful contact with an underage girl.

Thomas Shelby, 46, of Hanover Township, was arrested Tuesday at his home on Grace Avenue.

Police say Shelby was communicating with a 15-year-old girl via e-mail.

Investigators say the conversations were sexually graphic, and Shelby indicated that he wanted to meet the girl in the person.

Officials say the victim's father reported the incident to police.

Police searched Shelby's home on Tuesday and submitted five items to the Pennsylvania State Police Computer Crime Lab for analysis.

Investigators say Shelby was interviewed and admitted to the crime.

He's being held on $100,000 bail.
