CAMDEN, N.J. (AP) — Authorities say a New Jersey police officer has been charged with sexually assaulting a juvenile after a teen girl gave birth to his child.

The Camden County Prosecutor's office says that Camden County Detective Rafael Martinez Jr., of Blackwood, faces a sexual assault charge stemming from his relationship with an unidentified 15-year-old girl.

The official complaint says DNA tests performed by the state police based on samples from Martinez, the girl and the child show that Martinez is the father.

Martinez was arrested on Sept. 12 and has been suspended without pay.

It is not clear whether Martinez has an attorney to speak on his behalf.
