A Fairless Hills man has been arrested on allegations he used an Internet chat room to sexually proposition a detective posing as a child.

Christopher Brian McGee, 29, was charged with unlawful contact with a minor and criminal use of a communication facility. According to an affidavit, he repeatedly made contact with the "13-year-old girl," sending her explicit photos, posing nude in front of a Web cam, and suggesting they meet.

McGee allegedly used a neighbor's open wireless Internet connection. The attorney general's Child Predator Unit announced McGee's arrest Friday along with the arrests of three men from Lancaster and Carbon Counties and Ludlow, Mass. - Mari A. Schaefer
