Danielle Belford, 20, is accused of prostituting out a 16-year-old female, as well as engaging in prostitution herself, according to the release.

On May 12, an undercover detective from the county's prosecutor's office contacted Belford through her online advertisement and set up a meeting, authorities said.

During their meeting, Belford negotiated with the detective a sexual act involving herself and the 16-year-old victim, it was stated in the release.

At that point, Belford was placed under arrest.

Belford was charged with third-degree endangering the welfare of a child and fourth-degree promoting prostitution by procuring a prostitute for a patron. She was released on her own recognizance.

The 16-year-old victim was placed in the care of the New Jersey Division of Child Protection and Permanency, authorities said.

Detectives are continuing the investigation.

The arrest is the second in the past week involving a teen being used for prostitution.

On May 11, a New York pair were arrested in Elkton, Maryland and charged with using a 16-year-old Somerset County teen as a prostitute.
