Philadelphia Cop Had Sex With Teen, Offered Her $100

May 4, 2012— -- A veteran cop on the Philadelphia police force has been arrested for allegedly having sex with a 14-year-old girl in a motel room in a nearby town.

Anthony Dattilo, a 12-year veteran cop, was arrested Thursday on charges relating to the sexual assault of a teen girl whom he allegedly offered $100 to have sex with him.

Police were first directed to the Bensalem, Pa., motel room early Wednesday morning when relatives of a 14-year-old girl reported that she was sending text messages saying she was being held against her will by a man who was forcing her to have sex with him.

When police arrived at the motel in search of the possibly-abducted girl, Dattilo answered the door and identified himself as a Philadelphia cop.

Police found two women inside the motel room with Dattilo, including the 14-year-old and her cousin, a 21-year-old woman who had previous sexual relations with Dattilo in exchange for money, according to Bensalem Police Sgt. Andrew Aninsman.

While interviewing the women, police found that the 21-year-old had coerced the teenager to go with her to the motel room with Dattilo, telling her that she would be paid $100 for sex with him. The girl repeatedly said no, but was brought to the motel anyway, Aninsman said.

Dattilo allegedly had sex with the 21-year-old while the teen was forced to watch, and then proceeded to fondle the girl, which he was doing when police arrived, police said.

Dattilo was detained by police Wednesday and then released during the investigation, but was arrested on Thursday and is being held on $500,000 bail.

He faces charges including sexual assault and promoting prostitution, Aninsman said.

Philadelphia Police Commissioner Charles Ramsey confirmed Dattilo's arrest today to ABC News affiliate WPVI. He said authorities are working to remove Dattilo from the force.

Calls to the Bensalem and Philadelphia police departments were not returned.
